Abstract
Current and future WDM (Wavelength Division Multiplexing) optical systems for access and transport networks require stable, low-chirp and potentially low cost lasers emitting at predetermined (ITU-T grid) wavelengths. In addition advanced OTDM (Optical Time Division Multiplexing) systems require sources for high quality picosecond pulses on the transmitter side and optical devices for clock recovering on the receiver side The HDBR (Hybrid Distibuted Bragg Reflector) laser, also called FGL (Fiber Grating Laser) can meet all previous requirements.
