Polarization and amplitude hybrid modulation of longitudinally polarized subwavelength-sized optical
[期刊论文] 作者：LijiaoGuo,ChangjunMin,ShibiaoWei,XiaocongYuan,
来源：ChineseOpticsLetters 年份：2013
We present a method of both polarization and amplitude modulations on an incident beam to obtain a longitudinally polarized subwavelength-sized optical needle. A 4-f system with a spatial light modulator is used to generate experimentally a......
