Agility TLDM-6S SGDBR Tunable CW Laser, PMF, 20mW. Full C-Band.(Refurbished).
JDSU TLDM-6S SGDBR Tunable CW Laser Module, PMF, 20mW. Full C-Band with Wavelength Locker.(Refurbished).
The device consists of a six-section SG-DBR laser, an SOA, EA Modulator, Front Mirror, Gain, Phase, Rear Mirror, all integrated on the same InP chip. The SOA compensates on-state modulator loss and cavity losses caused by free carrier absorption in the tuning sections and allows power leveling with insignificant wavelength deviation. The integration of the laser and SOA active regions with the tuning and modulator sections of the device has been accomplished by using an offset quantum-well structure . In this simple integration technology the active region of the modulator uses the same bulk quaternary waveguide as the tuning sections of the laser. The Franz-Keldysh effect in the bulk waveguide material provides for larger spectral bandwidth as compared to the quantum-confined Stark effect. The composition of the bulk waveguide can be optimized to achieve high tuning efficiency for the laser and a target extinction ratio over the required wide spectral bandwidth for the modulator. An angled waveguide and wide-band anti-reflection coating at the output of the device were used to suppress the optical feedback to the SGDBR laser.
This Laser also integrated wavelength locker.
