摘要

Vertical cavity surface emitting laser (VCSEL) structure designed at 1.55 mu m was grown by low pressure metalorganic chemical vapor deposition method. The VCSEL structure contains top and bottom distributed Bragg reflector (DBR) and single cavity active layer. The DBR was grown with In_(0.53)Al_(0.14)Ga_(0.33)As and In_(0.52)Al_(0.48)As quarter lambda wavelength layer, alternatively. The growth temperature was as high as 750 deg C to prevent ordering and phase separation of the In_(0.52)Al_(0.48)As layer. The In_(0.52)Al_(0.48)As buffer layer was subsequently grown on the InP buffer layer in order to make an abrupt uniform interface. Unity reflectance was achieved at the center of 1.55 mu m with 35.5 pairs undoped DBR layers. The reflectance spectrum of undoped DBR showed a wide flat-band region (greater than 50 nm) where the reflectivity was more than 99.5
