Report developed under STTR contract for topic AF08-BT08. In the Phase II program, we have several important achievements related to silicon nanomembrane SiNM technology. We developed different SiNM transfer schemes that can enable development of intricate photonic devices on any substrate. In order to couple light efficiently into SiNM devices, we developed a subwavelength grating SWG coupler, that can achieve over 40 coupling efficiency using a fiber. Several components crucial for a conformal phased array antenna system, including compact modulator with highest slow down factor, PCW TTD lines with 216ps delay, 1x16 MMI power splitters for array functionality, printed PAA system operation etc were demonstrated. For the first time, demonstration of SiNM photonic devices on other substrates such as glass, Kapton etc was performed. These achievements will lead to the widespread development and use of SiNM based high performance photonic components in several air-borne and space-borne applications.
