摘要： A semiconductor light-emitting device having a plurality of semiconductor rods (9), each of which has a pn junction, formed on a semiconductor substrate (3) such that the plurality of semiconductor rods are arranged at a distance substantially equal to an integer multiple of the wavelength of light emitted from said semiconductor rod. With this structure, various novel optical devices such as micro-cavity lasers having an extremely small threshold current and coherent light-emitting devices having no threshold value can be realized.

摘要： A glass layer (2); is formed inside a silica glass tube (3) and another glass layer (1) having a refractive index higher than that of the abovementioned glass layer (2) is formed on said glass layer (2). After these glass layers (1,2) are formed, one end of the glass tube (3) is collapsed. While the internal pressure of the glass tube is being reduced below the atmospheric pressure, the glass tube is caused to collapse by heating, thereby yielding a preform for an optical fiber. The optical fiber produced from this preform has the difference in the refractive indices of the two orthogonal major axes (x, y) of at least 1.6 x 10 -4 and maintains the linear polarization plane.

摘要： An optical device having a material (21) exhibitive of an optical rectification effect is disclosed. The optical device utilizes direct current polarization which is induced in the material (21) by control light (25). The induction of the direct current polarization in the material by the control light(25) changes the refractive index and absorption spectrum of the material (21). This is based on the so-called electrooptic effect and Franz-Keldysh effect. The present invention provides the optical device according to which external incident light (23) can be modulated at high speed with the control light (25) by utilizing the change of the refractive index or the change of the absorption spectrum.
