Four different types of oxide VCSELs have been prepared for the transmitter modules; conventional-oxide and elevated-oxide-layer VCSELs with the oxide-aperture diameter of 6.6 and 10 μm, and their temperature dependence of the threshold current and turn-off transient responses have been measured. Approximately 10%-reduced both fall time and timing jitter mainly originating from the alleviated turn-off-induced abnormalities in the elevated-oxide-layer VCSEL transmitters contributed to achieve the fixed-current operation in the temperature range from 20 °C to 80 °C. Although the operating current of the elevated-oxide-layer VCSEL transmitter should be increased as the threshold current increases, a simple driving circuit owing to the fixed-current operating transmitter over a wide temperature range will bring a drastic energy saving in the optical data transmission system that incorporates VCSEL as a light source.</div></div> </li> <li class='list-group-item border-0 py-3 px-0'> <div class='row g-0 align-items-center mb-2'><div class='col-12 col-md-3 fullRecLabelEnglish fw-bold mb-2 mb-md-0'><span class='text-muted small'>Keywords</span></div><div class='col-12 col-md-9 leftDirection leftAlign'>laser cavity resonators; light sources; light transmission; optical transmitters; semiconductor lasers; surface emitting lasers; timing jitter; VCSEL transmitter; bit rate 1.25 Gbit/s; conventional-oxide structure; driving circuit; elevated-oxide-layer structure; energy saving; fixed-current operation; light source; optical data transmission; oxide-aperture diameter; size 10 mum; size 6.6 mum; temperature -20 degC to 80 degC; threshold current; timing jitter; turn-off transient responses; turn-off-induced alleviated abnormalities; vertical-cavity surface-emitting laser transmitter; Optical transmitters; Semiconductor lasers; Temperature dependence; Threshold current; Vertical cavity surface emitting lasers; Semiconductor lasers; temperature dependence; vertical-cavity surface-emitting lasers (VCSELs);</div></div> </li> <li class='list-group-item border-0 py-3 px-0'> <div class='row g-0 align-items-center mb-2'><div class='col-12 col-md-3 fullRecLabelEnglish fw-bold mb-2 mb-md-0'><span class='text-muted small'>fLanguage</span></div><div class='col-12 col-md-9 leftDirection leftAlign'>English</div></div> </li> <li class='list-group-item border-0 py-3 px-0'> <div class='row g-0 align-items-center mb-2'><div class='col-12 col-md-3 fullRecLabelEnglish fw-bold mb-2 mb-md-0'><span class='text-muted small'>Journal_Title</span></div><div class='col-12 col-md-9 leftDirection leftAlign'>Lightwave Technology, Journal of</div></div> </li> <li class='list-group-item border-0 py-3 px-0'> <div class='row g-0 align-items-center mb-2'><div class='col-12 col-md-3 fullRecLabelEnglish fw-bold mb-2 mb-md-0'><span class='text-muted small'>Publisher</span></div><div class='col-12 col-md-9 leftDirection leftAlign'>ieee</div></div> </li> <li class='list-group-item border-0 py-3 px-0'> <div class='row g-0 align-items-center mb-2'><div class='col-12 col-md-3 fullRecLabelEnglish fw-bold mb-2 mb-md-0'><span class='text-muted small'>ISSN</span></div><div class='col-12 col-md-9 leftDirection leftAlign'>0733-8724</div></div> </li> <li class='list-group-item border-0 py-3 px-0'> <div class='row g-0 align-items-center mb-2'><div class='col-12 col-md-3 fullRecLabelEnglish fw-bold mb-2 mb-md-0'><span class='text-muted small'>Type</span></div><div class='col-12 col-md-9 leftDirection leftAlign'><h2 class='mb-0 fw-semibold'>jour</h2></div></div> </li> <li class='list-group-item border-0 py-3 px-0'> <div class='row g-0 align-items-center mb-2'><div class='col-12 col-md-3 fullRecLabelEnglish fw-bold mb-2 mb-md-0'><span class='text-muted small'>DOI</span></div><div class='col-12 col-md-9 leftDirection leftAlign'>10.1109/JLT.2011.2175199</div></div> </li> <li class='list-group-item border-0 py-3 px-0'> <div class='row g-0 align-items-center mb-2'><div class='col-12 col-md-3 fullRecLabelEnglish fw-bold mb-2 mb-md-0'><span class='text-muted small'>Filename</span></div><div class='col-12 col-md-9 leftDirection leftAlign'>6072220</div></div> </li> <div class='list-group-item border-0 py-3 px-0'> <div class='row g-0 align-items-center'><div class='col-12 col-md-3 fw-bold mb-2 mb-md-0'><span class='text-muted small'>Link To Document</span></div><div class='col-12 col-md-9 leftDirection leftAlign'><a class='text-break' href='https://search.isc.ac/dl/search/defaultta.aspx?DTC=49&DC=1371348' target='_blank' rel=$ https://search.isc.ac/dl/search/defaultta.aspx?DTC=49&DC=1371348
