Summary form only given. We discuss a near-field optical storage system based on a semiconductor laser that is placed within 25-200 nm of a storage medium using flying head techniques commonly used in magnetic storage. The relatively large powers (>10 /spl mu/W) radiating from the laser enable data rates of larger than 10 Mbit/s while the vicinity of the head to media presents the possibility of...
Under pulsed operation, gain guided surface emitting lasers have exhibited long delay times and higher threshold current than for CW operation. This phenomenon is explained by assuming that adiabatic heating of the active region results in time evolution of the transverse mode guiding. The authors' theory suggests that a built in index guiding greater than 10/sup -2/ will stabilise the fundamental...
