Optical orthogonal codes (OOCs) are widely used
as spreading codes in optical fiber networks. In this paper,
a bound on the code size of 2-D OOCs with both at most
one-pulse per wavelength (AM-OPPW) and at most onepulse
per time slot (AM-OPPTS) is derived. Accordingly, two
constructions of optimal 2-D OOCs with both AM-OPPW
and AM-OPPTS are proposed via the generalized cyclotomic
classes. Furthermore, optimal 2-D OOC with AM-OPPW can
be also constructed by adding more codewords into the
2-D OOCs with both AM-OPPW and AM-OPPTS.
