Abstract
In this report, we describe 1.55 μm GalnAsP/InP strained quantum-well microdisk injection lasers operating with the minimum threshold current of 2.8 mA. The minimum diameter of 5 μm was realized by using methane-based RIBE. By reducing the diameter to less than 1.5 μm, a large spontaneous emission factor over 0.5 will be expected.
