M. Osinski et W. Nakwaski, EFFECTIVE THERMAL-CONDUCTIVITY ANALYSIS OF 1.55-MU-M INGAASP INP VERTICAL-CAVITY TOP-SURFACE-EMITTING MICROLASERS/, Electronics Letters, 29(11), 1993, pp. 1015-1016
An analytical approach is developed and appoied to investigate the the
rmal properties of 1.55 mum microresonator vertical-cavity surface-emi
tting lasers (VCSELs) mounted substrate-down. The results indicate tha
t difficulties with obtaining the CW operation of long-wavelength VCSE
Ls are primarily associated with intrinsic properties (such as low T0)
rather than with their thermal resistance.
