In this Letter, we propose a method of fabricating linear variable filters by ion beam etching with masking mechanisms. A triangle-shaped mask is designed and set between the ion source and sample. During the ion etching, the sample is moved back and fort
In this paper, a novel vertical cavity surface emitting laser (VCSEL) polarization modulation technique based on po-larization switching due to thermal heating in a single transverse mode class 10 G VCSEL at 1 310 nm is demonstrated experimentally. The in
