Abstract:

The first integrated multiwavelength laser based on an arrayed waveguide grating (AWG) fabricated on a silicon-on-insulator wafer is presented. It consists of Fabry-Perot cavities integrated with hybrid silicon amplifiers and an intracavity filter in the form of an AWG with a channel spacing of 360 GHz. Four-channel lasing operation is shown. Single-sided fiber-coupled output powers as high as 35 μW are measured. The device shows subnanosecond rise and fall times, and direct modulation at 1 GHz gives an open eye with an extinction ratio of 7.7 dB.

I. Introduction

Optical interconnects have the potential of replacing electrical interconnects for on-chip and off-chip applications as they offer higher bandwidth and lower power operation than their electrical counterparts [1] [2]. Wavelength division multiplexing (WDM) is one approach to take advantage of the bandwidth offered by optical interconnects [3], and multiwavelength lasers (MWLs) are an important part of WDM transmitters.
