This work presents a design technique to implement miniaturized cross-coupled bandpass filters in inline physical configurations based on triple-mode resonators. Triple-mode resonances are obtained by using integrated coaxial-waveguide cavity They consist of two coaxial conducting posts placed the sidewalls rectangular waveguide cavity. In proposed triplet, transmission zero (TZ) can be positio...

Filters play an irreplaceable role in virtually any type of radio frequency (RF)/microwave system today. With the recent rapid development and widespread use of various wireless communication systems, ever-more stringent requirements are posed on RF/ microwave filters – smaller size, higher performance, and lower cost are all simultaneously required today. Even more recently, multi-band operati...

Since the advent of laser, acousto-optic modulators have been an important tool for controlling light. Recent advances in on-chip lithium niobate waveguide technology present new opportunities these devices. We demonstrate a collinear modulator suspended film employing high-confinement, wavelength-scale waveguide. By strongly confining optical and mechanical waves, this improves figure-of-merit...

Waveguide gratings are used for applications such as guided-mode resonance filters and fiber-to-chip couplers. A waveguide grating typically consists of a stack single-mode slab grating. The filling factor the with respect to mode intensity profile can be altered via changing waveguide’s refractive index. As result, propagation length is slightly sensitive index changes. Here, we theoretically ...

A new generation waveguide spectrometer with broadband coupling capabilities has been developed. As opposed to previous devices, this attenuated total reflection (ATR) spectrometer is much simpler in design, is more chemically robust, and transmits light down to at least 400 nm. The attenuated total reflection element consists of a single-mode, planar integrated optical waveguide fabricated by ...

In modern microwave systems, a wide variety of frequency-selective devices are used, which performed according to certain technologies. Waveguide filters currently rapidly developing class functional devices. The manufacturing technologies, calculation methods and designs such is great. this paper, we consider band-pass filter on rectangular waveguide with cross section 35×15 mm, in which, inst...

This paper proposes a novel wavelength division multiplexer (WDM) demultiplexer design for dense WDM networks. The proposed demultiplexer consists of rectangular shaped periodic frequency filters connected in series. These rectangular filters can be formed with an apodized onedimensional (1-D) photonic crystal structure on a ridged semiconductor waveguide. A design example is given for such fil...

We fabricate and investigate wavelength selective components utilizing channel plasmon polaritons (CPPs) and operate at telecom wavelengths: a waveguide-ring resonator-based add-drop multiplexer (WRR-ADM) and a compact (3.75-microm-long) Bragg grating filter (BGF). The CPP waveguides represent 0.5-microm-wide and 1.3-microm-deep V-grooves in gold, which are combined with a 5-microm-radius ring ...

technology. They can be made on-chip along with an amplifier, mixer, multiplier, or other active circuit, or they can be printed separately on a ceramic substrate like alumina. The latter approach is usually most economical since real estate on III-V semiconductor wafers is costly compared to that of passive substrates, and they can easily be packaged alongside other MMICs and connected with bo...

Design narrow-band compact filters, based on high-quality waveguide-dielectric resonators with anisotropic materials is the subject of this paper. Filter represents a segment rectangular waveguide rotated around longitudinal axis 90 degrees and containing one or more dielectric inserts that completely fill resonator along narrow wall partially wide one. A distinctive feature proposed filter hig...
