The combination of Ultra-high-<i>Q<\/i> and small mode volume opens up new applications for wafer based resonators. In this talk I will first review the processing and passive optical properties of these devices and then describe their application to demonstrate micro Raman and micro OPOs on a chip as well as rare-earth-doped lasers on silicon. Finally, recent results concerning the observation of radiation-pressure-driven micro-mechanical oscillation at RF rates in these structures will be described.<\/p>\n","protected":false},"author":1,"featured_media":0,"template":"","class_list":["post-3947","physics_colloquium","type-physics_colloquium","status-publish","hentry"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.hmc.edu\/physics\/wp-json\/wp\/v2\/physics_colloquium\/3947","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.hmc.edu\/physics\/wp-json\/wp\/v2\/physics_colloquium"}],"about":[{"href":"https:\/\/www.hmc.edu\/physics\/wp-json\/wp\/v2\/types\/physics_colloquium"}],"author":[{"embeddable":true,"href":"https:\/\/www.hmc.edu\/physics\/wp-json\/wp\/v2\/users\/1"}],"wp:attachment":[{"href":"https:\/\/www.hmc.edu\/physics\/wp-json\/wp\/v2\/media?parent=3947"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
