We develop a new one-to-one correspondence between a two-dimensional (m?× n,?k,?ρ) optical orthogonal code (2-D (m?× n,?k,?ρ)-OOC) with AM-OPPTS (at most one-pulse per time slot) property and a certain combinatorial subject, called an n-cyclic holey packing of type m n . By this link, an upper bound on the size of a 2-D (m?× n,?k,?ρ)-OOC with AM-OPPTS property is derived. Afterwards, we employ combinatorial methods to construct infinitely many 2-D (m?× n,?k,?1)-OOCs with AM-OPPTS property, whose existence was previously unknown. All these constructions meet the upper bounds with equality and are thus optimal.
