Digital D-Type Isolator
Single-Mode Digital D-Type Module with Optical Isolator
Innovative Photonic Solutions’ proprietary SingleMode Spectrum Stabilized Laser Diode features high output power with ultra-narrow spectral bandwidth and a circularized and collimated output beam. Designed to replace expensive DFB, DBR, fiber, and external cavity lasers, the Single-Mode Spectrum Stabilized Laser offers superior wavelength stability over time, temperature (0.007 nm/ºC), and vibration, and is manufactured to meet the most demanding wavelength requirements.
The Digital OEM D-Type module comes standard with a circularized and collimated output beam, integral laser line filter pack, internal thermistor and TEC, linear tracking photodiode and ESD protection, and UART I/O interface.
