Title: Surface waviness measuring device
Inventor: NAKAJIMA MASAHITO
IPC: G01B11/245
Filed: 1986-05-31
Abstract: PURPOSE:To enable highly accurate measurement of surface waviness of a specimen, by giving a beam of illuminating light vertical to a surface of a specimen from directly above and constructing so that illuminating beam and reflecting beam are aligned on the same optical axis without receiving effect of vertical motions of the specimen. CONSTITUTION:A beam of light L from a laser light source 21 provides a beam of light l12 from directly above onto a surface of a specimen M through polarized beam divider 23, 1/4lambda plate 24. Its reflected beam l13 returns along the same optical axis and is incident onto light-dividing prisms 26, 27 through lambda-plate 24, divider 23, half-mirror 25. Here, now when a specimen M makes vertical motions, as far as the surface retains its flatness, the optical axis of the beam l13 coincides with that of the beam l12. Normally as the vertical motions cover a few mum and represent extremely small distance as compared with some several hundred mm of distance between the specimen M and the prism 27, no effect is inflicted on a light beam shape on the prism 27. The same situation is applied to the prism 26. Consequently, the vertical motions of the specimen M exerts no effect on waviness measurements of the surface.

Filed: 1982-07-19
Abstract: PURPOSE:To obtain the negative resistance green colored light emitting electrodes with high light emitting output by a method wherein the donor concentration is specified at low value not exceeding the residual acceptor concentration to grow an epitaxial layer forming a P type inversion layer. CONSTITUTION:When an N type GaP epitaxial layer 3 is liquid phase grown on an N type GaP substrate 1, a doping Te melt is utilized as donor impurity. Next the melt is doped with Zn as an acceptor impurity exceeding Te and slowly cooled down to grow P layer. When an N type epitaxial layer 3 starts to be grown, a P type inversion layer 2 is formed. The acceptor concentration of the P type inversion layer 2 was 2X10<16>/cm<-3>. When the donor concentration is not exceeding the acceptor concentration, the P type inversion layer 2 with P-N- P-N constitution is formed displaying the current-voltage characteristic in the normal direction with the negative resistance region. Through these procedures, the concentration of the N type epitaxial layer as the light emitting region may be specified at the low donor concentration obtaining the negative resistance green colored light emitting elements with high light emitting output.

Abstract: PURPOSE:To prevent the deterioration in the quality of an optical signal caused from the reduction of modal noise by regulating the forming of fiber length to 1/2DELTAv.a so that the mode dispersion of the fiber is performed to minimize the coherence. CONSTITUTION:A multi-longitudinal laser output transmitted from a semiconductor laser 2 of a laser diode module 1 is condensed by a lens 3, delayed for a prescribed amount by a fiber 4 and inputted to a connector 5.

As a result, the coherence of the semiconductor laser 2 is made small sufficiently at the part of the connector 5, the interference of the light in each mode due to the mode conversion is decreased and generation of modal noise is suppressed.
