## Abstract Variableβweight optical orthogonal code (OOC) was introduced by GβC Yang for multimedia optical CDMA systems with multiple quality of service (QoS) requirement. In this article, new infinite classes of optimal (__u, W__, 1, {1/2, 1/2})βOOCs are obtained for __W__={3, 4}, {3, 5} and {3,

## Abstract Several direct constructions via skew starters and Weil's theorem on character sum estimates are given in this paper for optimal (__gv__, 5, 1) optical orthogonal codes (OOCs) where 60ββ€β__g__ββ€β180 satisfying __g__ββ‘β0 (mod 20) and __v__ is a product of primes greater than 5.
