This paper focuses on the performance limits of a tunable-cavity Fabry-Perot filter (FPF) implemented using MEMS technology. This is a versatile device capable of many functions, including light modulation and high precision sensing. Our goal is to explore challenges and opportunities in implementing tunable-cavity filter using MEMS technology. Thermal stability and effects of fabrication imper...

The South Pole Imaging Fabry-Perot Interferometer (SPIFI) is the first instrument of its kind-a direct-detection imaging spectrometer for astronomy in the submillimeter band. SPIFI's focal plane is a square array of 25 silicon bolometers cooled to 60 mK; the spectrometer consists of two cryogenic scanning Fabry-Perot interferometers in series with a 60-mK bandpass filter. The instrument operate...

In this letter, a passive microring-resonator-coupled semiconductor laser structure is proposed. The weakly coupled high-Q microring resonator provides a strong mode-selection filter and could considerably extend the effective cavity length of a conventional Fabry–Perot laser. The side-mode suppression ratio, the linewidth and the frequency chirp of this laser are dramatically improved comparin...

By controlling the thickness of the grating depth with chemical beam epitaxy (CBE) growth time, we report in this letter the design and performance of an integrated tunable detector. A carefully designed tunable active filter, which allows only one below threshold Fabry-Perot mode for operation, is integrated with a waveguide detector. The full tuning range of this kind of tunable device can no...

Fabry-Perot Filters are major candidates for use as demultiplexers in wavelength division multiple access networks. In this paper we investigate the crosstalk limitations of such filters, compare their performances, and optimize the filter design to minimize the crosstalk degradation. 1 Bol.h witli the al)()rt;l.orlo for informltaiou a.icl I)ecision Ssleties. ilT.
