Modulight creates semiconductor lasers for medical devices, satellites, automotive LIDARs, fiber lasers, telecom diagnostic equipment, industrial diagnostic machines, and many others. Modulight 40,000-sq.ft diode laser fab was opened in 2001. Modulight has over 18 years’ experience of diode lasers: high-power CW, QCW and pulsed lasers, transmitter lasers, DFBs, lasers for OTDR, LIDAR, and many others.
At Modulight, we also assemble modules and systems in-house. We are experts in designing, testing, and manufacturing lasers for advanced solutions. This requires custom mounting, built-for-use test setups, or semiconductor masks that are used for in-wafer testing.
Laser development begins with design and epitaxial growth. Grown wafer lots are thoroughly tested in terms of performance and reliability. Modulight’s wafer processing facility is compatible with GaAs and InP based materials of 2″–4″ size; most of our processed wafers are 3″. All the processing steps are controlled and recorded by Modulight Database (MLDB) according to our quality policy, supporting full traceability.
The processed wafers are cleaved into arrays of individual emitters, laser bars. The facets of bars are passivated and coated to achieve a certain reflection on the front and back. The arrays are then used as bars or further diced into single emitters.
Modulight chip development path:
1. Fill in the custom product inquiry
2. Modulight will schedule call to review requirements with customer
3. Agree joint development project
4. First prototype design and joint validation
5. Design update or production ramp-up
6. Volume production scale-up
