发布时间： - 摘要：In this paper, We present the scheme of a bipolar spectrally encoded optical code division multiple access system, using balanced transmission and Mach-Zehnder encoder chains. The optical CDMA system closely approach WDM performance. The main issues were speckle from multiple users, shot noise, and true code orthogonality within a non-coherent system.

发布时间： - 摘要：This paper presents two design schemes for optical fiber transmission system for radar signal. In the first scheme, the digital and analog signals are transmitted respectively. The second scheme adopts all digital transmission. The system based on the first scheme has been succesfully developed and used in the radar of a certain type, and the system based on the second scheme is in the course of development. This paper also describes the key technologies for the system, and provides several optical fiber transmission schemes for radar signal suitable for long distance applications.关键词：radar signal;optical fiber transmission;multichannel transmission;TDM

发布时间： - 摘要：Two types of Yb 3+ doped fibers were manufactured by MCVD method, including step SM fiber and double-cladding fiber. The Yb 3+ doped fiber laser operates at 1 030 nm with 68% slope efficiency and a >40 mW output. A 15 dB small signal gain is obtained at 1 053 nm in a Yb 3+ doped fiber amplifier.关键词：Yb 3+ doped fiber;manufacture;laser properties
