Photodetectors for microwave applications: a review and trends
نویسندگان
چکیده
After a review of conventional microwave photodetectors, this paper is dealing with the difficulties to fulfill applications requirements (responsivity, bandwidth, power), when the bandwidth is extended up to the millimeter wave frequency range. Up to date solutions are given and the validity of a new concept, the PIN photodiodes evanescently coupled to a multimode waveguide, is demonstrated.

متن کاملChapter 2 . High - Frequency InAIAs / InGaAs Metal - Insulator - Doped Semiconductor Field - Effect Transistors ( MIDFETs ) for Telecommunications
InAlAs/InGaAs Modulation-Doped Field-Effect Transistors (MODFETs) on InP have recently emerged as an optimum choice for a variety of microwave and photonics applications. This is because the outstanding transport properties of InGaAs have yielded devices with very low-noise and high-frequency characteristics. Unfortunately, the low breakdown voltage of InAlAs/InGaAs MODFETs on InP (typically le...
