Title: Optical semiconductor element
Inventor: SATO TOSHIHIKO
IPC: H01S5/026
Filed: 1993-02-23
Abstract: PURPOSE:To obtain a wavelength conversion element having a high wavelength conversion efficiency, by providing an optically transparent region in the wavelength conversion element with respect to the shorter light wavelength than the one corresponding to the band gap of a semiconductor material in a bulk state. CONSTITUTION:In order that the second higher harmonic of a light is absorbed in a quantum box region 100 of a semiconductor material, it is required that the level in the conduction band of the material whereto electron in the valence band of the material is subjected to a transition by its resonant excitation is in an inoccupied state. In the conduction band laid in the quantum box, no electron level other than discrete levels 50, 51 exists, and therefore, such a transition as a transition 62 is not generated. Also, since the level 50 is occupied by electron in the conduction band, no transition to the level 50 is generated. Further, the level 51 has the height whereto no transition of electron can get even though electron in the conduction band is excited. Therefore, there is no level which resonates to the light having energy hnu in the quantum box 100. Further, no second higher harmonic is absorbed in a barrier region 101 since its band gap is larger than the energy hnu of the second higher harmonic.

Title: Nonlinear optical element

IPC: G02F1/355
Filed: 1993-02-23
Abstract: PURPOSE:To enable the taking out of a change in refractive index by a cubic nonlinear optical effect with a high sensitivity by forming a nonlinear optical material which has cubic nonlinearity and optical-rotatory dispersion characteristic. CONSTITUTION:This nonlinear optical material 21 has the cubic nonlinearity and optical- rotatory dispersion characteristic and its optical path length is set in such a manner that the plane of polarization rotates 90 deg. when reference light 22 of a wavelength lambda1 is transmitted therethrough as linearly polarized light in a perpendicular direction by a polarizer 24. Then, the reference light 23, the plane of polarization of which is rotated by 90 deg. to be in the horizontal direction is shut off by an analyzer 25 having the bearing in the perpendicular direction when control light 23 is not made incident. On the other hand, the control light 23 is strong light and, therefore, the light induces the nonlinear optical effect in the nonlinear optical material 21 when the control light 23 of a wavelength lambda2 is made incident as the linearly polarized light in the perpendicular direction on the nonlinear optical material 21 by the polarizer 24. Namely, the nonlinear optical effect is induced on the plane of polarization of the reference light 22 in the state where the plane of polarization of the reference light 22 inclines from the plane of polarization of the control light 23 and, therefore, the reference light 22 is eventually made into elliptically polarized light. A perpendicular component is, therefore, generated in the reference light 22 and is passed through an analyzer 25.
