{"product_id":"optical-modulation-von-edgar-huante-ceron","title":"Optical Modulation:","description":"\u003cp\u003eMeasurements of thallium and indium doped Silicon-On-Insulator rib waveguides show optical absorption at a wavelength of 1550nm, dependent on the charge state of the associated deep-level. Therefore, it is possible to use this effect to modulate waveguide transmission by means deep-level occupancy change induce by local depletion and\/or injection of free-carriers. A one-dimensional model based on the generation and recombination process described by the modified Shockley-Read-Hall (SRH) mechanism was developed using MATLAB programming language in order to compute the optical absorption of a 1550nm wavelength as a function of the density of neutrally-charged thallium or indium centers. In addition, the influence of indium, as a dopant in silicon (utilizing the Impurity Photovoltaic  Effect), as a means to increase the efficiency of a thin film silicon solar cell was investigated using the same samples.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783846586723\"\u003e\u003ch3\u003eby Controlling the Charge State of Deep Impurity Levels in Silicon\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783846586723","offer_id":39476258799709,"sku":"9783846586723","price":79.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/adad4487-a0f1-4cf1-8d80-e146ac827331.jpg?v=1769148373","url":"https:\/\/shop.autorenwelt.de\/products\/optical-modulation-von-edgar-huante-ceron","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
