摘要
A strategy to contact organic lasers is proposed. Without the need for thick transport layers that keep the optical mode away from the contacts waveguide losses similar to those of structures without contacts can be achieved. The key to this concept is to position the contacts in the intensity minima of the TE2 waveguide mode. This is accomplished by optical buffers outside the contacted device. Structures based on this idea are demonstrated and the waveguide losses are analyzed. A reduction of the waveguide losses by more than an order of magnitude compared to a device without optical buffers is observed.
