title: Red-green-blue laser emission from cascaded polymer membranes.
abstract: Red-green-blue polymer laser emission is achieved in a free-standing membrane device consisting of three distributed feedback cavities. The polymer membrane is fabricated via interference lithography and a simple lift-off process. Multilayer structures can be assembled by cascading several polymer membranes. Thus optically pumped, simultaneous, red-green-blue laser emission is obtained from a three-layer cascaded membrane structure. This simple and low-cost fabrication technique can be used for compact, integrated laser sources.
