Towards SP generation/amplification at telecom wavelengths using transverse-magnetic polarized semiconductor diode lasers
Last modified: 2012-01-03
Abstract
We propose and demonstrate that properly designed semiconductor laser active regions can compensate the large losses that plasmons experience in the telecom wavelength range. We show that laser devices based on tensile-strained quantum wells - hence emitting transverse magnetic polarized light - are suitable for plasmon generation via electrical injection. Experimental evidence is obtained using near-field microscopy measurements.
