Abstract

Advances in system architecture for wideband Integrated-Service-Digital-Network (ISDN) has resulted in large demand for low cost and reliable opto-electronics components for the upcoming high-bit-rate optical-fiber communication network. This paper presents recent progress in the design of a high-speed LED transmitter which can modulate LEDs at > 560Mb/s with an active bias circuit and high a.c. current drive (~200mA). It achieves excellent extinction ratio (~15 dB) and launches -22 dBm power into single-mode fiber. The LED device has the advantages over the lasers because of low cost, temperature stability and high reliability. It requires less-complicated driver circuit so the LEDs are ideal light sources in term of ease of maintenance for high volume applications like the subscriber loop and local area data link networks.
