Abstract
A low-threshold, p-type substrate laser array emitting at a wavelength of 1.3 μm is useful for high-bit-rate parallel optical data link applications, such as switching and computing systems.1–2 The laser needs to be fabricated on a p-type substrate because a p-common assembly of the laser array and NPN transistor IC chips is essential for the high-frequency operation of the transmitter module.
