Photo-Detectors Integrated with Resonant Tunneling Diodes

We report on photo-detectors consisting of an optical waveguide that incorporates a resonant tunneling diode (RTD). Operating at wavelengths around 1.55 μm in the optical communications C band we achieve maximum sensitivities of around 0.29 A/W which is dependent on the bias voltage. This is due to the nature of RTD nonlinear current-voltage characteristic that has a negative differential resis...

IXYS Offers Discrete 1700V IGBT Copacks With New Soft Recovery SONIC-FRD Diodes

IXYS announced that in keeping up with ambitious growth plans in the IGBT market, its European Operation, a leader in Direct Copper Bond (DCB) module packaging technology, located in Lampertheim, Germany has extended its portfolio of IGBT modules down in power to cover the high volume cost sensitive segment of the market. This new family of DCB based IGBT Modules are housed in the industry stan...

WLAN Substrate Integrated Waveguide Filter with Novel Negative Coupling Structure

A fourth-degree Substrate Integrated Waveguide (SIW) crossed coupled band pass filter for WLAN band is designed by using a new negative coupling structure. It consists of two U shape microstrip lines on top and bottom planes with via holes at the center of them. This paper investigates the phase characteristics of negative and positive coupling structures and their effects. The design, fabricat...

Improving Blue InGaN Laser Diodes Performance with Waveguide Structure Engineering

To enhance lasers’ power and improve their performance, a model wasapplied for the waveguide design of 400 nm InGaN/InGaN semiconductor laser, whichis much easier to implement. The conventional and new laser structures weretheoretically investigated using simulation software PICS3D, which self-consistentlycombines 3D simulation of carrier transport, self-heating, and opt...
