High temperature operation of athermal widely tuneable laser with simplified wavelength control for WDM-PON systems

High temperature operation of athermal widely tuneable laser with simplified wavelength control for WDM-PON systems

A simplified control system is described which uses only three point calibration to maintain the wavelength of the ITU channels of an uncooled DS-DBR laser, spaced at 50GHz, over the full C-band. Wavelength is controlled mode-hop free over a temperature range of 45° to 80°C.
