Abstract

Fast multiwavelength monitoring was realized by injection-locking a Fabry-Perot laser diode. Simultaneous wavelength monitoring of two WDM channels with resolution of 0.005 nm was demonstrated with a response time of 3 ns. As the response time for each measurement is only 3 ns, the number of channels can be increased by adjusting the modulation pattern with low duty cycle with a long zero level.
