The design of hybrid and pure grating filters with two passbands (bicorn) is explained. The limitations on their performance due to temperature fluctuations and fabrication difficulties are considered. We show that hybrid bicorns with a 500-nm-broad 20-dB rejection band and a 10-pm FWHM with 300-pm peak separation are conceivable. They are useful for telecommunication applications. In addition, these filters are shorter than 1 mm and thus well adapted to micro-optics and integrated optics.
