Abstract
A temperature-tunable Fabry-Perot filter made of silicon has been developed and applied for simultaneous spectral filtering and wavelength monitoring of a directly modulated DFB laser. This novel device decreases the dispersi on penalty of a cost-effective dense wavelength-division-multiplexing (DWDM ) transmitter in a long-haul transmission link, Moreover, it allows the ope rating wavelength of the transmitter to be accurately monitored in real tim e.
