Abstract
A multiple-wavelength GaInAsP/InP microlaser with microdisk radiuses from 10 m to 10.6 m laterally coupled into a bus waveguide are fabricated by standard photolithygraphy and inductively coupled-plasma (ICP) etching techniques. The lasing wavelengths are 1533 nm, 1541 nm, 1551 nm and 1555 nm at the CW injection current of 10 mA for the four microlasers. The proposed multiple-microlaser array would be useful for realizing compact wavelength division multiplexing (WDM) light source for optical interconnects.
Highlights
Optical wavelength division multiplexing (WDM) technology has attracted great attentions for noticeably increasing the bandwidth density and communication capacity of a single link and makes it more feasible to realize monolithic PICs

Summary
Optical wavelength division multiplexing (WDM) technology has attracted great attentions for noticeably increasing the bandwidth density and communication capacity of a single link and makes it more feasible to realize monolithic PICs. To meet the increasing requirement of optical interconnection link, laser sources which could emit signals of several wavelengths with equal intervals are indispensable [1]. To meet the increasing requirement of optical interconnection link, laser sources which could emit signals of several wavelengths with equal intervals are indispensable [1] This sort of multi-wavelength laser (MWL) source can be realized by cascading several microlasers on one SOI bus waveguide as shown in [2]. The lasing spectra of four microlasers at the same injection current of 10 mA are given and compared
