Abstract

A grating-assisted surface-emitting laser transmitter with image-forming capability has been fabricated. The laser transmitter consists of an InP-InGaAsP distributed Bragg reflector ridge laser emitting at 1.5 μm, a semiconductor optical amplifier and a computer-generated holographic out-coupler. The area of the out-coupler is 80 μm×80 μm. The image produced by the out-coupler is focused at 3 cm above the laser surface and each circular spot has a diameter of 0.6 mm.
