Pj. Poole et al., THE FABRICATION OF A BROAD-SPECTRUM LIGHT-EMITTING DIODE USING HIGH-ENERGY ION-IMPLANTATION, IEEE photonics technology letters, 8(9), 1996, pp. 1145-1147
High-energy ion implantation is used to spatially modify the bandgap o
f a 1.5-mu m laser structure to fabricate a broad spectrum light emitt
ing diode (LED), An increase in the emission full width half maximum (
FWHM) from 28 nm to 90 nm is observed, An absorbing section at one end
of the device is used to suppress lasing operation and remove Fabry-P
erot noise.
