Aminian, Mahdi. In this thesis we propose the use of photodiodes fabricated in planar technologies to address the detection problem in these applications. In this thesis we focused on Ge thanks to its versatility and ease to use in the clean room. The main advantage of this material is in fact a good compatibility with Silicon and standard CMOS processes. In our pure Ge approach, Ge is grafted onto Si Ge-on-Si , achieving high responsivity at wavelengths of nm and higher.

Avalanche photodiode - Wikipedia

An avalanche photodiode APD is a highly sensitive semiconductor photodiode that exploits the photoelectric effect to convert light into electricity. From a functional standpoint, they can be regarded as the semiconductor analog of photomultipliers. Typical applications for APDs are laser rangefinders , long-range fiber-optic telecommunication , and quantum sensing for control algorithms. New applications include positron emission tomography and particle physics. By applying a high reverse bias voltage typically — V in silicon , APDs show an internal current gain effect around due to impact ionization avalanche effect. In general, the higher the reverse voltage, the higher the gain.

The avalanche photodiode at high frequencies.

Mottaleb Hossain. There is a need in emerging smart lighting concepts for a high-speed sensing capability to enable adaptive lighting smart spaces and visible light communication. One approach to address this need is to design and manufacture a novel complementary-metal—oxide—semiconductor CMOS compatible, cost-effective detector array and readout circuit ROIC that incorporates integrated waveguide detectors and avalanche photodiodes APDs.

The visible light communication VLC system has been considered as an alternative indoor communication method for future networks. The VLC system requires highly sensitive receivers. However, the excess noise generated within the APD limits its sensitivity.

It is really providing good and quality information.

Perhaps offer some more advanced course in the future? Maybe an advanced fiction specialization? Either way, good introductory course.

Good one, if you are confused where to put your commas and to learn tenses.
