Abstract
A low-threshold 1.3- mu m InGaAsP MQW laser array was fabricated on a p-type InP substrate taking compatibility with n/p/n-type laser-driver circuits into account. The laser has a p/n-type current-blocking structure and is made entirely by metal-organic chemical vapor deposition (MOCVD). A 10-channel laser array with a threshold current as low as 3.2+or-0.2 mA (per element) and a slope efficiency of 0.27+or-0.01 W/A is obtained.<>Keywords
