An ultra-wideband (UWB) power divider is designed in this paper. The UWB performance of this power divider is obtained by using a tapered microstrip line that consists of exponential and elliptic sections. The coarse grained parallel micro-genetic algorithm (PMGA) and CST Microwave Studio are combined to achieve an automated parallel design process. The method is applied to optimize the UWB pow...

─ In this paper, a novel microstrip power divider with a new technique for nth harmonic suppression is presented. This technique is based on using front coupled tapered compact microstrip resonant cell (FCTCMRC) that inserted into a quarter-wavelength transmission line of the conventional Wilkinson power divider. This cell is used to obtain high harmonic suppression. The proposed power divider ...

In this paper, the design of compact and high performance parallel coupled line wideband bandpass filter using image parameter method are proposed. The filter mainly comprising one-stage parallel coupled line and two open stubs are designed and implemented on commercial RT/Duroid 5880 substrate. The equivalent circuit of the proposed structure is initially derived by using the image parameter m...

In this publication we present the results of a detailed study into directly written multimode waveguides for astronomical applications. We show that waveguides up to 100 μm across can be inscribed with the cumulative heating form of this technique. The waveguides have 2 concentric guiding regions which are elliptical; a core that has an average ellipticity of 1.1±0.1 and an outer cladding with...

This paper gives an overview on recent achievements in micromachined technology for millimeter and submillimeter-wave applications, from 130 to 750 GHz. The micromachined components presented include the first ever submillimeter-wave MEMS devices, namely a 500600 GHz 3.3 bit phase shifter and a 500-750 GHz waveguide MEMS switch, a 0.02 dB/mm loss waveguide technology for the 220-330 GHz band wi...

We experimentally demonstrate an on-chip silicon 1×2 switch that routes 8 data channels on 4 modes and 2 polarizations. The insertion losses are < 8dB, and the crosstalk values are below -15dB. The 8 channels are tested with a 72-Gb/s signal. OCIS codes: (230.3120) Integrated Optics; (130.4815) Optical switching devices.

An ultrasmall (<10  μm length) polarization converter in InP membrane is fabricated and characterized. The device relies on the beating between the two eigenmodes of chemically etched triangular waveguides. Measurements show a very high polarization conversion efficiency of >99% with insertion losses of <-1.2  dB at a wavelength of 1.53 μm. Furthermore, our design is found to be broadband and t...
