	A design of beam shaping unit for 193nm lithography illumination system using angular spectrum theory (EI CONFERENCE) 会议论文 OAI收割 6th International Symposium on Precision Engineering Measurements and Instrumentation, August 8, 2010 - August 11, 2010, Hangzhou, China 作者: Zhao Y.; Zhang W.; Zhang W.; Li S.; Gong Y. 收藏 \| 浏览/下载：20/0 \| 提交时间：2013/03/25 Off-axis illumination (OAI) technology is widely used to enhance resolution for deep ultraviolet lithography. The realizing methods of OAI include geometrical optics method and physical optics method. However the former has the disadvantage of weak intensity distribution controlling ability and the latter introduces simulation errors evidently when dealing with near field diffraction propagation. A diffractive optical element (DOE) designing method using plane wave angular spectrum theory is presented in this paper. Several kinds of OAI modes at near field away from DOE can be realized and simulation errors and the size of illuminator are also reduced. According to studying the relationships of the sampling point distance of DOE light beam propagation distance and the structure of the beam shaping unit a method of determining the designing parameters is discussed. Using this method several illumination modes are realized and simulation results show that all diffraction efficiencies reach up to 84%. The method of DOE manufacturing is analyzed at last and it is proven to be feasible. 2010 SPIE.
	Rearrangeable nonblocking 88 matrix optical switches based on extended banyan network (EI CONFERENCE) 会议论文 OAI收割作者: Zhang Y. 收藏 \| 浏览/下载：31/0 \| 提交时间：2013/03/25 Based on the CROSSBAR network (CN) and the BANYAN network (BN) 8 matrix optical switch two new rearrangeable nonblocking constructions of extended BANYAN network (EBN) are proposed for implementing 88 optical matrix switch. The interconnection characteristics of these two types of rearrangeable nonblocking EBN were studied optical insertion loss of 4.6 dB and the logic program for driving switching units was provided. The calculated insertion loss was 3.3 dB for 88 optical matrix switch. Silica waveguide 88 matrix optical switch was designed and fabricated according to the calculated results. The silica waveguide propagation loss of 0.1 dB/cm and waveguide-fiber coupling loss of 0.5dB/point were measured. With the fabricated 87times cross-talk of -38 dB polarization dependent loss of 0.4 dB averaged switching power of 1.6 W and switching time of 1 ms were achieved. A basic agreement between experimental results and theoretical calculated values was achieved.
