This paper is a theoretical analysis of mirror tilt in a Michelson interferometer and its effect on the radiant flux over the active area of a rectangular photodetector or image sensor pixel. It is relevant to sensor applications using homodyne interferometry where these opto-electronic devices are employed for partial fringe counting. Formulas are derived for radiant flux across the detector f...

Quasiparticle dynamics and energy resolution of STJ single-photon detectors are described. A new readout, the RF-STJ, is presented and its implementation as an mm-wave detector is tested using an on-chip hot–cold source. r 2006 Elsevier B.V. All rights reserved.

Background: To determine the basic physical and dosimetric properties of a new synthetic single-crystal diamond detector and its application for relative small field dosimetry. Materials and Methods: The pre-irradiation dose required to stabilize detector response, dose rate dependence, photon and electron energy dependence, temperature dependence and angular dependence of MicroDiamond detector...

In the UCLA plasma beat wave accelerator, a high intensity two frequency CO2 laser ~l1510.6 mm, l2510.3 mm! is used to drive a large amplitude relativistic plasma wave. The plasma wave acts as a moving phase grating and scatters the incident pump waves into Stokes and anti-Stokes sidebands ~v12vp , v21vp!. The observation of these sidebands in the forward direction confirms the presence of the ...

This paper presents an effective design methodology and flow, which is validated through three mmwave/sub-mm-wave amplifiers: including W-band LNA with NF=7dB, W-band PA with PAE >11% and D-band amplifier with gain>20dB. The CMOS based amplifiers can be integrated with III-V materials to form heterogeneous integration, such as COSMOS, to achieve the best performance for various applications.
