摘要： In a display unit which makes coherent light perform scanning on a screen to display an image, it is necessary to rotate a polygon mirror at ultrahigh speed for display of a high resolution image such as HDTV, and therefore, a high-performance polygon mirror must be employed, and further, noise and power consumption during rotation of the polygon mirror cause problems. Mirrors for multiple reflection (6a) and (6b) are inserted in a coherent light scanning optical system, whereby plural scanning lines can be obtained while one plane of the polygon mirror (5) scans one line of coherent light, leading to reduction in the rpm of the polygon mirror.

摘要： A laser light source (10) has semiconductor lasers (1) and a waveguide tube (3) for propagating emission light from each of the semiconductor lasers (1). The semiconductor lasers are arranged on the upper end on the incident surface (31) side of the waveguide tube such that the emission light (4) from each of the semiconductor lasers enters into the waveguide tube from one end surface (31) of the waveguide tube and exits from the other end surface (32) of the waveguide tube. The structure can realize a small-sized laser light source having high output and capable of outputting emission light having uniform emission light intensity distribution.

摘要： An optical waveguide device is provided that can reduce external interference noise. The optical waveguide device includes a substrate, an optical waveguide formed on the substrate, a periodic polarization inversion region formed on the optical waveguide, and an optical thin film formed in a portion of the optical waveguide. The optical waveguide (refractive index: N2) and the optical thin film (refractive index: N1) differ in refractive index dispersion, and the magnitude relationship between the refractive indexes is reversed depending on wavelength. The relationship N1>N2 is established for light having a shorter wavelength, while the relationship N2>N1 is established for light having a longer wavelength.

摘要： A surface emitting laser (100a) includes an active layer (3) disposed on a semiconductor substrate (2a), and a pair of upper and lower electrodes (5,6) for injecting carriers into the active layer (3). The plane surface of the lower electrode (6) is shaped into a star so that injection of current into the active layer (3) from the lower electrode (6) is carried out with a high density at the center of the lower electrode (6) and with a low density at its periphery part. In the surface emitting laser (100a), the density distribution of the carriers injected into the active layer corresponds to the power distribution of light inside the active layer. Thereby, hole burning due to an increase in the current density in the region of the active layer corresponding to the peripheral part of the electrode is avoided, and the transverse mode stability during high output operation is significantly enhanced to improve high-output characteristic.
