This book first provides a general introduction to the physics of intersubband transition in GaN\/AlN MQWs and its device applications especially all-optical switches operating at commutation wavelength. Later on, the issues with regard to conventional MOVPE were comprehensively discussed and analyzed. As a solution of these problems, a growth technique called ¿pulse-injection method¿ was employed to achieve intersubband absorption at 1.55-µm wavelength range. The effects of growth parameters on the properties of intersubband transition were investigated and discussed.  Various types of AlN-based waveguides, including ridge, high-mesa, and spot-size converter, with GaN\/AlN MQWs absorber were designed and fabricated. The saturation of intersubband absorption which determines the functionality of all-optical switch was clearly observed. This book demonstrated the potential of MOVPE-grown GaN\/AlN MQWs for intersubband devices operating at communication wavelength.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783659171772\"\u003e\u003ch3\u003eMetalorganic Vapor Phase Epitaxy and Fabrication\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783659171772","offer_id":39489982627933,"sku":"9783659171772","price":79.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/b3e2c114-1812-4423-bc11-671dd7d3753b.jpg?v=1772862321","url":"https:\/\/shop.autorenwelt.de\/products\/1-5-m-gan-aln-mqws-intersubband-all-optical-switches-von-hassanet-sodabanlu","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
