Abstract: "Selectively oxidised
vertical-cavity lasers emitting at 1294 nm using InGaAsN/GaAs quantum wells
which exhibit continuous wave operation at and above room temperature are
reported for the first time. The lasers employ two n-type A10.94GaO.06As/GaAs
distributed Bragg reflectors each with a selectively oxidised current aperture
adjacent to the optical cavity, and the top output mirror contains a tunnel
junction to inject holes into the active region. Continuous wave singlemode
lasing is observed up to 55 degrees C. These lasers exhibit the longest
wavelength reported to date for vertical-cavity surface lasers grown on GaAs
substrates."
This 2000 report from Electronics Letters
was cited 9 times in current journal articles indexed by ISI
during July-August 2002. One other report published in the last two years and
indexed in the Hot Papers category of Engineering managed to attract more
citations during this bimonthly count, but none has yet matched Choquette et
al.'s overall citation total as of the July-August tally. Prior to the
most recent bimonthly period, citations to the paper have accrued as follows:
May-June 2002: 5 citations
March-April 2002: 4
