The HIGH SPEED PHOTODETECTORrefers to the photogenerated current generated by the photodetector under the illumination of incident light, and the dark current can be defined as the leakage...
Light can excite plasmons on the metal surface, and the plasmons can further excite high-energy hot electrons. These hot electrons can cross the metal/semiconductor Schottky junction to form a...
Photodetectorsare usually divided into photodetectors and pyroelectric detectors according to their working principles and structures. Photodetectors include vacuum photoelectric devices...
There are 4 types of multimode fiber-coupled laser diodes:
Single Emitter: When the laser diode chips are individually assembled on the submount and individually packaged in the laser diode...
The DFB laseruses a grating optical filter device based on the FP laser so that the device has only one longitudinal mode output. The characteristics of this type of device are: large output...
In a typical photoconductive antenna-based terahertz time-domain spectroscopy system, the photoconductive sampling method is used to collect terahertz time-domain signals. Photoconductive...
Due to the popularity of the Internet and video-on-demand services, the capacity of photon network systems must be increasing. The semiconductor photodetector converts the optical signal into an...
This paper demonstrates a high-speed broadband photodiode based on a vdW p-WSe2/n-Ge heterojunction.
Photodiodeswith long n-Ge regions of low doping (LD) concentration exhibit fast response...
photodetectorsare often used to measure the waveform of short pulsed laser light. When making this type of measurement, there are two important details to be aware of: the problem of saturation...
Photodetection at mid-to-far-infrared (Mid/Far-IR) wavelengths has been of great interest in recent years in many industrial, military, and scientific applications. Atmospheric trace greenhouse...
