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.

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.
