10Gbit/s Bidirectional Data Transmission with Monolithic VCSEL–PIN Transceiver Chips
نویسندگان
چکیده
We report the monolithic integration, fabrication, and electro-optical properties of AlGaAs– GaAs-based transceiver (TRx) chips for 850 nm wavelength optical links with data rates of multiple Gbit/s. Avoiding the use of external fiber coupling optics and using a single buttcoupled multimode fiber (MMF) with 50 or 62.5μm core diameter, low-cost bidirectional communication in halfand even full-duplex mode is demonstrated. Based on a verticalcavity surface-emitting laser (VCSEL) and a monolithically integrated p-doped–intrinsic– n-doped (PIN) photodiode (PD), such TRx chips are capable of high-speed bidirectional data transmission with MMFs over distances of a few hundred meters. Standard MMF networks can thus be upgraded using monolithic VCSEL–PIN transceiver chips which can handle data rates of up to 10Gbit/s.
