Submicron diffraction gratings etched on an InP/InGaAsP waveguide edge for wavelength division multiplexing

Journal Article

2D monolithic grating spectrometers for dense wavelength division multiplexing (WDM) show considerable promise to extend the usable bandwidth of optical fibers. Their performance is fundamentally dictated by the grating which is used. First order gratings will theoretically improve the performance of monolithic WDM devices, since WDM devices based on first order gratings do not suffer from an inherent tradeoff between efficiency and broadband operation.
