Abstract

Using thin membrane InP microdisc lasers heterogeneously integrated on a Silicon on Insulator (SOI) substrate having a broad band analog modulation bandwidth of 11GHz, we demonstrate analog direct modulation with radio data signals (64 and 256-QAM, 20M Symbols/sec at 5GHz RF carrier). The demonstration shows the potential of the microdisc laser as a low-energy analog optical transmitter with EVM penalties of 3.6% and 4.2% for 64-QAM and 256-QAM respectively and the low biasing currents for both DC (4mW) and RF (0.1mW) signals, which are compatible with
signals and currents which can be supplied by a simple CMOS driving chip.
