The design and optimization of a novel InP-based monolithically integrated optical channel monitor are presented. The device, which comprises a flat-field echelle grating and a slab photodetector array, can monitor signals in 40 wavelength channels separated by 100 GHz. The authors' simulations show that the novel design can result in a device of a smaller size and with a flatter and wider passband than those reported previously. It also features simpler fabrication without the need for output waveguides, thus eliminating issues related to fabrication-sensitive waveguide couplings. The shape of the slab waveguide detectors and the vertical layered structure are optimized to obtain a low crosstalk and a low polarization dependence.
