ScholarBank@NUS Repository. https://doi.org/10.1109/IPGC.2008.4781504 | Abstract: | We transform a linearly polarized Gaussian beam into a radially polarized doughnut beam using an eight-segment spirally varying retarder (SVR) at wavelength of 808 nm, and obtain < 96% of polarization purity at far field distribution. The SVR is designed based on the linear birefringence of α- barium borate (α-BBO) crystal and fabricated using a dry etching technique. | Source Title: | 2008 IEEE PhotonicsGlobal at Singapore, IPGC 2008 | URI: | http://scholarbank.nus.edu.sg/handle/10635/71536 | ISBN: | 9781424429059 | DOI: | 10.1109/IPGC.2008.4781504 |
