ABSTRACTThe phenomenon of second harmonic generation has been studied from the earliest days of nonlinear optics.[l] To date the most impressive results in terms of conversion efficiency for as low an input power as possible have been obtained in channel waveguides made from inorganic materials.[2] However, when their second order nonlinearities (10s of pm/V) are compared with those of organic materials (10s → 100s pmn/V), it is clear that organic materials should eventually produce much better harmonic conversion efficiencies.

Cerenkov-type optical second-harmonic generation (SHG) in organic-crystalline waveguides has been investgated. Various techniques for the fabrication of organic-crystalline waveguides are described. Planar and channel waveguides have been fabricated using an organic nonlinear optical crystal (−)2-(α-methylbenzylamino)-5-nitropyridine (MBANP). Visible blue light has been obtained in an MBANP rib waveguide using a laser-diode source. Theoretical analysis of Cerenkov-type SHG in planar waveguides is made, and a simple analytic expression for second-harmonic power is derived. Optimum conditions for attaining high conversion efficiency are discussed on the basis of the theoretical calculations.
