Title: Phase shift type distributed feedback semiconductor laser
Inventor: AOKI MASAHIRO
IPC: H01S5/00
Filed: 1996-05-14
Abstract: PROBLEM TO BE SOLVED: To realize element structure of a phase shift type distributed feedback semiconductor laser which can be formed by a simple method, by making the difference of propagation constants of two regions and the sum of lengths of regions where a diffraction grating is not formed satisfy a specified relation. SOLUTION: In a distributed feedback type semiconductor laser of wavelength 1.3μm band, the layer structure has a buried type diffraction grating 13 which is partly formed. In this structure, propagation constants of optical waves are a little different from each other, in the region 18 where the buried type diffraction grating exists and the region 19 where it does exist, in a resonator having a length of Lc. Between the difference Δβ of the propagation constants and the sum Ls of the region 19 where the grating is not formed, in order to satisfy a relation 0.4π<Δβ.Ls<0.6π, Ls is so adjusted that the product Δβ.Ls becomes equal to π/2.  Therefore, an equivalent λ/4 shift type diffraction grating can be obtained, so that a high output distributed feedback type semiconductor laser capable of a stable single mode, and an optical module mounting the laser can be realized by very easy technique.

Filed: 1990-05-10
Abstract: PURPOSE:To facilitate the maintenance of a pressure roll by retracting the pressure roll from a dielectric roll in the beginning of the rotation of the dielectric drum until an initial toner image which is formed on the surface of the dielectric drum reaches a transfer area. CONSTITUTION:If toner 7 which should not be stuck originally is stuck on the surface of the dielectric drum 1 in the beginning of the rotation of the dielectric drum 1, the pressure roll 4 is retracted from the dielectric drum 1 during the passage of the toner 7 in the transfer area. Further, the pressure roll 4 is pressed against the dielectric drum 1 before a toner image which is formed nearly on the surface of the dielectric drum 1 reaches the transfer area T through a destaticization device, an ion recording head, and a developing unit, Then the toner image is transferred to a transfer material which is sent timing with the arrival of the toner image at the transfer area. Consequently, the toner 7 is never transferred to the pressure roll 4, whose maintenance is facilitated; and a back copy of the toner 7 to transfer paper and a defect in separating the transfer paper are prevented.
