Abstract
Official abstract text for this publication.
A vertical cavity surface emitting laser (VCSEL) nanoscope is provided. The VCSEL nanoscope combines a VCSEL with a nano-scale aperture using a support member to separate the aperture from the VCSEL emission face. The resulting device is a useful near-field probe with a wide variety of applications.
First claim
Opening claim text (preview).
The invention claimed is: 1. A near-field optical device comprising: a vertical cavity surface emitting laser (VCSEL) having an emission wavelength; a support member having a base and a tip, wherein the support member is substantially transparent at the emission wavelength; wherein the base of the support member is disposed on the VCSEL such that radiation emitted from the VCSEL propagates toward the tip of the support member; a screen disposed on the tip of the support memb…
