Abstract
The authors propose a novel multiwavelength simultaneous monitoring (MSM) circuit that uses the wavelength crossover properties of an arrayed-waveguide grating (AWG). The MSM circuit is locked to a reference wavelength and can achieve 10 MHz resolution and 30 MHz stability for 24 h. Multiwavelength simultaneous monitoring is successfully demonstrated using four tunable lasers.Keywords
