Abstract
A grating spectrometer integrated monolithically in the InGaAsP system with a photodiode array for a dense WDM system is presented for the 1 .5 mum wavelength region. The chip provides more than 30 wavelength ch annels with a spacing of 4 nm, a channel crosstalk of approximately - 15 dB, an internal photodiode efficiency of 90% and a photodiode capac itance of 0.33 pF. The chip needs no optical adjustments. It is theref ore well suited to mass production.
