Flat-Top Optical Comb Filter Optoplex provides flat-top optical comb filter based on its optical interleaver technology. In contrast with traditional Fabry-Perot cavity-based comb filter, Optoplex's comb filter is capable of transmitting modulated DWDM signals with its passband width available anywhere down to a few picometers. Both the filter channel spacing (FSR) and filter duty cycle (3-dB bandwidth to FSR ratio) can be specified by customers. Based on Optoplex's patented technologies of micro-optics and phase modulation through thin-film coating, the flat-top comb filter is a purely passive device characterized by minimal temperature dependence, flat-top passband, high channel isolation, low PDL, and uniform insertion loss. The product is Telcordia GR-1221 qualified. Tunable Edge Filter Tunable edge filter belongs to 2-port optical tunable filter product platform. Instead of using bandpass filter in the 2-port tunable filter, the tunable edge filter utilizes a low-pass or long-pass interference filter. By changing the incident angle of the light beam, the cut-off wavelength will be tuned. The typical performance of a long-pass tunable edge filter is shown below. Tunable Passband Filter Through combining a low-pass tunable edge filter with a long-pass tunable edge filter, one can achieve a new type of tunable passband filter whose passband width is variable while its center wavelength is tunable. With such a device, you can Change passband width Tune center wavelength |
