Design of fiber-integrated tunable thermo-optic C-band filter based on coated silicon slab

Background: Optical filters are required to have narrow band-pass filtering in the spectral C-band for applications such as signal tracking, sub-band filtering or noise suppression. These requirements lead to a variety of filters that offer thermo-optic effect for optical switching, however, some of which without proper thermal and optical efficiency. Methods: In this paper we propose a tunable...

Shaping of ultrashort optical pulses by using an integrated acousto-optic tunable filter.

Reshaping of ultrashort optical pulses at 1.53 ,um by using an integrated acousto-optic tunable filter is reported. Control of the optical pulse shape is accomplished by adjusting the different radio-frequency electrical signals driving the acousto-optic filter. This is to our knowledge the first demonstration of ultrashort pulse shaping using an integrated-optic device and establishes a new ap...

Tunable Active Dual-Band Bandpass Filter Design Using MMIC Technology

Abstract— The inductor-less designing of monolithic tunable active dual-band bandpass filter is presented in this study. Biasing voltages signify main role. They can control the center frequency and quality factor. Using four biasing voltages and cascading two similar filters leads to dual-band bandpass filter. By keeping the gain constant, the center frequency shift is 200 MHz. Regardless cons...

Effect of metal coating in all-fiber acousto-optic tunable filter using torsional wave.

Torsional mode acousto-optic tunable filter (AOTF) is demonstrated using a metal-coated birefringent optical fiber for an improved robustness. The changes in acoustic and optical properties of a metal-coated birefringent optical fiber induced by the thin metal coating were analyzed experimentally and theoretically. The filter wavelength shift is successfully explained as a result of combined ef...
