摘要
The key limitation to dense Wavelength Division Multiplexing (WDM) systems is the receiving end since laser linewidths are typically less than 1 angstrom. By reverse biasing the p-i-n diode region, we demonstrated dual functionality of wavelength-tunable Vertical-Cavity Surface-Emitting Lasers (VCSELs) as wavelength-tunable Resonant Cavity Photodetectors (RCPs) with linewidths less than 2.5 nm. Additionally, we have fabricated wavelength-tunable Resonant Cavity PhotoTransistors (RCPTs) with linewidths as narrow as 1.7 nm. Wavelength-tunable RCPTs are capable of high quantum efficiency, narrow linewidth, and high-speed operation, making them ideal devices for WDM receivers.
