Abstract
Linewidth reduction has been observed in a distributed Bragg reflector (DBR) laser with a second-order grating when an external cavity is fo rmed with the vertical emission. The external cavity consists of a len gth of optical fiber which is brought close to the top of the laser. D isplayed linewidths low as 26 kHz have been measured. To the authors' knowledge, this is the first report of linewidth reduction via vertica l emission from a laser diode.
