Metal-cavity surface-emitting nanolasers
Metal-cavity surface-emitting micro/nanolasers are proposed and demonstrated. The design uses metals as both the cavity sidewall and the top/bottom reflectors and maintains the surface-emitting nature. As a result of the large permittivity contrast between the dielectric and metal, the optical …
