Abstract :
The authors reports the first high-reflectivity multilayer dielectric mirrors fabricated from MOVPE-grown AlGaInAs/InP for long-wavelength operation. Mirrors have been fabricated from 40-layer structures using 1.3 mu m composition AlGaInAs which exhibit reflectivities as high as 95% in the wavelength range 1.55-1.7 mu m.
