    摘要: A non-diffracting beam generator converts coherent light from a semiconductor laser into a small, intense, non-diffracting beam, which is directed into a non-linear optical element. The non-linear optical element converts this beam to light of a different wavelength. The non-linear optical element is a bulk element, not having an internal waveguide, and not requiring precise alignment of the non-diffracting beam. The non-diffracting beam preferably has a length matching the thickness of the non-linear optical element.

    摘要: A wavelength conversion device employs an axicon lens to form Bessel beams of signal light and pump light, which are directed into an anisotropic nonlinear optical crystal. The signal light and pump light are both polarized parallel to the uniquely determined Z-axis of the anisotropic nonlinear optical crystal, the Z-axis being oriented perpendicular to the beam axis. The axicon lens is configured to refract the signal light and pump light at angles such that a phase matching condition is satisfied in the anisotropic nonlinear optical crystal, and converted light, also polarized parallel to the Z-axis and having a new wavelength, is generated.

    摘要: To provide a microoptical system for free-space optical interconnection capable of relaxing the arrangement accuracy of a light source and a photodetector. A point light source and a photodetector are interconnected each other by first and second imaging lenses and focused Gaussian beams. In this case, the point light source, first imaging lens, second imaging lens, and photodetector are positioned so that the effective beam radius .omega..sub.2 of a focused Gaussian beam on the first interconnecting lens is larger than the effective beam radius .omega..sub.4 of a focused Gaussian beam on the second imaging lens.
