摘要： A wavelength monitor monolithically integrated with a tunable LD is disclosed. The wavelength monitor includes at least two filters, each filter having a different periodic transmission spectrum. A transmittance of the first filter, and another transmittance of the second filter at a grid wavelength attributed to a WDM system forms a combination which is specific to the grid wavelength but different from other combinations at other grid wavelengths.
