A novel class of unipolar optical orthogonal codes (OOCs), with ideal in-phase cross correlation for spectral-amplitude coding optical code-division multiple-access systems based on projective geometry (PG) is proposed. Large flexibility in cross-correlation control makes the proposed OOC family an excellent candidate for applications that require a large number of users. The construction permits arbitrary large OOC families. Novel electronically controllable PG-OOC encoder-decoder architectures based on arrayed waveguide grating and semiconductor optical amplifier gates are proposed as well.
