About Bay Photonics
Q. What does
Bay Photonics do?
A: Bay Photonics specialises in the design, assembly, and packaging of photonics. We provide Research and development and low- to medium-volume manufacturing services for applications in communications, sensing, quantum, and advanced photonics systems.
“At Bay, we make the tiny tech that enables things like high speed internet, lasers and other cool light-based gadgets”
Elliot Prowse – Associate R&D Engineer
Q: Do you offer Design and Development?
A: Yes. We provide full in-house design and simulation: optical, RF, mechanical, thermal, and environmental. We offer high-reliability hermetic hybrid packaging and integration solutions. Furthermore we offer advice on PIC design, rapid prototype, and design for volume manufacture.
Q: Do you work with companies outside the UK?
A: Yes. We collaborate with international partners across Europe, North America, and Asia. We support remote project management and global logistics.
Q: Where are you based?
A: We’re located in EPIC, Torbay, Devon, UK — at the heart of the South West’s photonics cluster. Our facilities are designed for precision assembly, hermetic sealing, and testing.
Q: How can I visit or tour your facilities?
A: Visits are welcome by prior appointment. Please contact us to arrange a tour or technical discussion by giving us a call on +44 (0)1803 714744 or emailing us at info@bayphotonics.com
Capabilities and Services
Q: What types of devices can you package?
A: Our experience covers semiconductor lasers, detectors, modulators, photonic integrated circuits (PICs), fibre assemblies, and hybrid optoelectronic devices. We work with both prototype and production-level assemblies.
Q: What type of packaging does Bay Photonics offer?
A: We offer a wide range of packaging such as 14-pin, 7-pin butterfly packages, TO-Cans (Transistor Outlines), custom hermetic packages and fibre-attached and optical packages.
For photonic integrated circuits (PICs) and hybrid modules, we offer fibre alignment and attachment for single, multi or array coupling.
Q: Do you provide hermetic sealing?
A: Yes. Hermetic is a core competency. We offer a range of sealing techniques including seam sealing, solder sealing, and glass-to-metal or ceramic-to-metal interfaces.
Q: Can you assist with design for manufacture (DfM)?
A: Absolutely. Early engagement allows us to advise on package selection, thermal management, alignment tolerances, and materials compatibility – reducing development time and improving yield.
Q: What testing and inspection services do you offer?
A: We provide optical and electrical tests, environmental stress screening, and leak testing. In-house inspection includes X-ray, microscopy, and mechanical metrology.
Projects and Collaboration
Q: What is your typical project size or duration?
A: We handle anything from short feasibility studies to multi-year development programmes. For research collaborations, we can operate under NDAs.
Q: Do you support grant-funded or collaborative R&D projects?
A: Yes. Bay Photonics has participated in numerous Innovate UK and European research programmes, particularly in quantum, communications, and sensing technologies.
Q: How do you ensure confidentiality?
A: projects can be protected by non-disclosure agreements (NDAs). We operate secure data storage and restricted-access laboratory areas.
Practical Information
Q: How can I request a quotation?
A: Send a brief project summary, drawings, and any relevant specifications to info@bayphotonics.com We’ll arrange a call with our sales manager and engineers to clarify requirements and provide a detailed quotation.
Q: Do you provide cleanroom assembly?
A: Yes. Our cleanroom facilities support automated assembly, die handling, pick, place and wire bonding, surface-mount, precision optical alignment, welding, and standard and custom hermetic sealing under controlled environments.
Hybrid co-packaging is available – micro, bulk, and fibre optics integrated with ceramics, high-speed electronics and TECs.
Q: What is your typical lead time?
A: Lead times vary by complexity and material availability. TBC CHECK
Q: Can you handle component procurement and supply chain?
A: Yes. We can either work with customer-supplied parts or manage procurement through our qualified supplier network

Photonics Basics
Q: What is photonics?
A: Photonics is the science and technology of using light – photons – instead of electricity to carry information or perform tasks. It’s used in everything from the internet’s fibre networks to sensors, medical imaging, and quantum technologies.
Q: What is a semiconductor?
A: Semiconductor is a material that can act as both a conductor and an insulator, depending on how it’s treated. It’s the foundation of modern electronics and photonics — used to make devices like lasers, LEDs, and photonic chips that control or generate light.
Q: How is photonics different from electronics?
A: Electronics use electrons (electrical current) to process and transmit signals, while photonics uses photons (light particles). Photonics can transmit data much faster and with less energy loss, which is why it’s central to high-speed communications and precision sensing.
Q: What does ‘packaging’ mean in photonics?
A: Packaging means putting delicate optical and electronic components together in a way that protects them and keeps them precisely aligned. It can involve bonding chips, attaching fibres, sealing the device, and adding electrical connections — all while maintaining optical performance and reliability.
Q: Why does hermetic sealing matter?
A: Hermetic sealing protects photonic devices from moisture, oxygen, and other contaminants. This is especially important for lasers and sensors that need to perform reliably over many years, or in harsh environments like space or defence applications.
Q: What are photonic integrated circuits (PICs)?
A: Photonic integrated circuits are chips that use light instead of electricity to carry signals. They can combine many optical functions – such as lasers, modulators, and detectors – on a single chip, just like electronic circuits combine transistors.
Q: What industries use photonics?
A: Photonics is everywhere – in telecommunications (fibre optics), healthcare (medical imaging, diagnostics), manufacturing (laser processing, sensors), autonomous vehicles (LiDAR), and emerging fields like quantum computing and secure communications.
Q: What does Bay Photonics do in this field?
A: Bay Photonics helps turn photonic and optoelectronic designs into real, working devices. We specialise in assembling and packaging the components that make photonics systems stable, reliable, and ready for use in research or production.
