As the detector is placed just in the evanescent field of the waveguide, the detector can only absorb a fraction of light intensity. This is very well desired as it allows the creation of a stationary wave within the waveguide, which requires that the reflected light intensity is comparable ...
With a very inexpensive combination of a miniature Hg blacklight as an excitation source, a colored plastic sheet as the emission filter, and an integrated blue sensitized photodiode-operational amplifier as the detector (totaling <$100 in hardware cost), we were able to achieve a limit of ...
of a stealth fighter jet, but this is still a piece of consumer electronics from more than a decade in the past. So let’s crack it open and take a look at what goes on inside a radar detector that’s only a few years away from being old enough to get its own driver’s license...
We anticipate that our work opens new possibilities to generate LWIR light sources and perform nonlinear frequency conversion-based applications in LWIR on an integrated photonics platform. First, the waveguide fabrication technique introduced in this work is simple, flexible and universal to variousχ(2...
A relative transmittance of the optical waveguide shows that the propagated light maintains the wide spectrum. A planar diode is used as photodetector. The proposal-integrated structure shows that light impinges directly on the depleted zone, improving detection and performance of the diode. Finally, ...

THz waveform synthesizers for coherent control of linear and nonlinear interactions with matter are often realized via spectral phase and/or amplitude shaping. Integrated versions of such devices require as fundamental building blocks power splitters and there are a number of different options ranging fro...
