Abstract/Description: Laser on a penny; cleaved coupled-cavity laser is seen here through a scanning electron microscope. To fabricate the device, a semiconductor laser is cleaved into two nearly equal parts. The output of the cleaved coupled-cavity can be tuned electronically from one ultrapure single-frequency to another, promising significant advances in lightwave communication.
