The invention relates to a switchable bandpass filter (3). In particular, the invention relates to a narrow-band bandpass filter (3) which can be switched over a broad frequency band and has two filter elements (22, 24) designed with microstrip line technology, which filter is suitable for use as a cosite filter in a compact design which is ...

Gradient Index Bandpass Filters
Optical Interference Coatings, 1992The performance of filters having sinusoidal refractive index profiles have been published by various authors1. In general, these filters have a strong reflection at the design wavelength and offer the promise of no harmonics at any wavelength2. Further, these refractive index profiles may be superimposed with each other creating multiple stopbands ...

Bandpass Filters for Communications
Optical Interference Coatings, 1995There is considerable interest today for filters for fiber optics telecommunications are in the Near Infra-red spectral area. Activity is centered about 1550 nm. Components for Wavelength Division Multiplexer filters used with fiber amplifiers require very high transmission of certain selected wavelengths with very low transmission of an adjacent ...

The acousto-optic bandpass filter is a device whereby one or more bands of optical wavelengths may be selected for further transmission. In this device, all light within the optical bandwidth of operation is first coupled from the core mode of a optical fiber to a specific cladding mode by a long-period photo-induced grating.

Capacitive Switching Bandpass Filters
2010The objective of this chapter is to design and characterize tunable bandpass filters that integrate the capacitive switch (or the DC-contact switch) into the CPW transmission line structure. A capacitance tuning bandpass filter is designed. The filter consists of two series coupled resonators and a series of coupling capacitors and shunt capacitors in ...
