Abstract
Channelled substrate planar (c.s.p.) GaAlAs-GaAs d.h. lasers with p-type blocking layers have been prepared using a combination of organometallic pyrolysis and liquid-phase epitaxy. The use of o.m.p. to prepare the channelled blocking layers allows the growth of thin first confining layers necessary for good mode control. Devices produced in this manner are both linear and single-mode to power levels in excess of 14 mW.
