Abstract
We have developed a laser diode that provides a spot size ratio of 1:2.1, making it promising for optical printing and recording.1 A schematic view of the developed laser diode is shown in Fig. 1. It is fabricated by using metal-organic chemical vapor deposition, as were the previously reported buried stripe lasers.2 The structure has a flared stripe with a twininjection striped modulation region at the base of the flared structure. The main electrode and the subsidiary electrode for the modulator are separated by channels formed in the p-type GaAs contact layer and in the Au electrodes.
