Design, Fabrication and Characterization of Very Small Aperture Lasers

摘要：

An L-shaped aperture with 15nm ultra-high optical resolution and strong field enhancement is designed. The very small aperture lasers (VSAL) with L-and rectangular aperture are fabricated, and their confined optical fields are detected using an apertured scanning near-field optical microscope (SNOM). For L-aperture VSAL,when the drive current is 28mA, the power output can reach 1.049μW,while the power output of the rectangular aperture VSAL at most reaches 0.078μW. In the experiment based on the apertures in Au film on glass substrate, the peak intensity of C aperture is about 10 times over the square aperture. The experimental results indicate that the unconventional L-and C-aperture have stronger field enhancement than rectangular and square aperture.
