Morton B. Panish helped develop semiconductor lasers using a double heterostructure. A narrow-gap active layer between wider-gap semiconductor layers confines injected charge carriers and guides the emitted light. This combined electronic and optical confinement lowered the threshold sufficiently for continuous operation at room temperature.[ref]
