| Popis: |
Laser-amplifier photonic integrated circuits (PIC’s) with high coupling efficiency between the laser and amplifier elements, using the InP material system, have been described previously [l-3]. Surface emitting laser amplifier devices have also been reported in the GaAs system using second order Bragg reflector gratings [4]. In the present work we describe a strained layer MQW laser-amplifier PIC intended for use as a high power source for pumping erbium doped fiber amplifiers (EDFA’s) at 1.48 micron wavelength. Multiple quantum well (MQW) optical amplifiers have extremely high saturation output powers [5,6], making them very suitable for high power applications. |
