Increasing scope and applications of integrated optics necessitates the development of automated techniques for physical design of optical systems. A key area of integrated optic design is waveguide routing, which currently lacks the level of automation found in VLSI design. Unlike VLSI, where signal nets are routed with metal layers and vias, integrated optics is a planar technology and lacks ...

Magnetically controlled waveguide-based phase shifters are desirable for their high performance, but bulky and heavy, thus cannot be easily integrated with printed circuit board (PCB) based circuits. To tackle this, substrate-integrated waveguide (SIW) technology has been utilized, which brings the to a standard PCB, requires large numbers of vias as well multiple cavities in substrate ferrite ...

Presence of Foreign object debris (FOD) at airport runways is an immense threat to flight safety. Such objects may cause potential damage to the aircraft especially during the take off and landing. This paper introduces the design of a low-cost Ka-band FOD radar sensor adopting state-of-the-art system-on-substrate (SoS) approach. Contrary to the reported single-layer SoS design approach, multi-...

─ Antipodal linear tapered slot antenna (ALTSA) for 60 GHz communications is presented in this paper. To obtain a high gain, dielectric loading in addition to the corrugation structure is applied to the ALTSA. The use of substrate integrated waveguide (SIW) technology allows a highly efficient, compact and low cost planar design. The antenna is designed and simulated in an electromagnetic field...

We report two novel strategies to integrate magneto-optical oxides on oxidized silicon and SOI platforms based on strip-loaded waveguide structures. By using conventional waveguide fabrication and thin film deposition techniques, strip-loaded waveguides for magneto-optical non-reciprocal phase shift (NRPS) applications can be integrated on a silicon platform. As a demonstration, two structures,...

A thin-film InGaAs/GaAs edge-emitting single-quantum-well laser has been integrated with a tapered multimode SU-8 waveguide onto an Si substrate. The SU-8 waveguide is passively aligned to the laser using mask-based photolithography, mimicking electrical interconnection in Si complementary metal-oxide semiconductor, and overlaps one facet of the thin-film laser for coupling power from the laser...

Recently, has emerged a n ew technology, substrate integrated waveguide (SIW) [1] [2], it has been applied successfully to the conception of planar compact components for the microwave and millimeter waves applications [3] [4]. Our study concerns the analysis of right bends of rectangular waveguides under SIW technology by the HFSS code, in order to simulate different chamfrain positions, throu...

This research proposes a substrate-integrated waveguide (SIW) cavity sensor to detect several chemicals using the microwave frequency range. The frequency response of the presented SIW sensor is switched by filling a very small quantity of chemical inside of the fluidic channel, which also causes a difference in the effective permittivity. The fluidic channel on this structure is either empty o...
