City of Light: The Story of Fiber Optics

A comparison was made of the photoluminescent (PL) intensities of n‐type InP and GaAs at room temperature. The PL intensity for InP was over 100 times greater than for comparably doped GaAs. The effect of surface recombination velocity S on the PL intensity was evaluated numerically. When this evaluation is applied to the PL intensity ratios of n‐type InP and GaAs it shows that S for n‐type InP is sufficiently small to eliminate significant influence of nonradiative surface recombination on the observed PL intensity.

Evidence for low surface recombination velocity on n‐type InP

Room‐temperature cw operation has been achieved for stripe‐geometry double‐heterostructure Ga0.12In0.88As0.23P0.77/InP diode lasers emitting at 1.1 μm. The heterostructures were grown by liquid‐phase epitaxy on melt‐grown InP substrates, and stripes were defined by using proton bombardment to produce high‐resistance current‐confining regions.
