摘要： The present invention concerns a method for constructing a light coupling system wherein a grating is manufactured on the surface of a multimode waveguide and defines the entrance of the waveguide for an incident light beam, said grating comprising a repetition of patterns. The grating is defined by a set of parameters comprising: • grating period (P), separating two adjacent patterns, • grating depth (d) between the highest and the lowest point of the pattern, • incident angle mean value (θ) of the incident light with respect to the waveguide. The method comprises a step of optimization of the set of parameters to obtain an optimized second set of parameters, in order to obtain a transmission efficiency (Ce) of the incident light into said waveguide for the first or the second diffractive order exceeding 35% for unpolarized light, or exceeding 50% for polarized light, at a given wavelength of the incident light.

摘要： A method for driving a plasma display panel includes applying an erasing pulse, a reset pulse and a scan pulse respectively in each of an erasing period, a reset period and a scan period. In a reset period, a reset pulse with a waveform of a sloped ramp pulse is applied to the scan electrode. The sloped ramp pulse induces a discharge between the scan electrode and the address electrode in the middle of the period while the pulse voltage increases. This prevents extremely high discharges between the scan electrode and the address electrode and improves the contrast of the display. An apparatus that implements such method is also disclosed.

摘要： A method and apparatus for optical spectral power monitoring using a time-division-multiplexed detection scheme. The apparatus uses a wavelength-dispersing means (120) such as a diffraction grating to separate an optical signal into multiple spectral channels, and an array of beam-manipulating elements (140) positioned to correspond with the spectral channels. The beam-manipulating elements are individually controllable so as to direct the spectral channels into an optical detector (150) in a time-division-multiplexed sequence. The apparatus may further employ a polarization diversity scheme for polarization-insensitive operation. This enhances the spectral resolution of the apparatus while providing improved accuracy in spectral power detection. Spectral power monitors constructed according to the present disclosure are well-suited for WDM optical networking applications.

摘要： This invention provides a novel wavelength-separating-routing (WSR) apparatus that uses a diffraction grating (101) to separate a multi-wavelength optical signal by wavelength into multiple spectral channels, which are than focused onto an array of corresponding channel micromirrors (220). The channel micromirrors are individually controllable and continuously pivotable to reflect the spectral channels into multiple output ports. As such, the inventive WSR apparatus is capable of routing the spectral channels on a channel-by-channel basis and coupling any spectral channel into any one of the output ports. The WSR apparatus of the present invention may be further equipped with servo-control and spectral power-management capabilities, thereby maintaining the coupling efficiencies of the spectral channels into the output ports at desired values. The WSR apparatus of the present invention can be used to construct a novel class of dynamically reconfigurable optical add-drop multiplexers (OADMs) for wavelength division multiplexing (WDM) optical networking applications.

摘要： A symmetric optical switch for selectively switching wavelength channels between four optical inputs. The symmetric optical switch includes two dispersive elements receiving optical inputs from respective optical fibers where the optical inputs are dispersed into a plurality of wavelength-separated input channels. The symmetric optical switch also includes a plurality of circulators disposed on each optical fiber and a switching array mechanism that receives the plurality of wavelength-separated input channels from each of the dispersive elements. The shutter array simultaneously switches one or more pairs of the wavelength-separated input channels between four optical inputs. Each circulator that is disposed on the associated optical fiber operates with the shutter array to form an eight port device so as to independently switch wavelength channels.

摘要： The present invention aims at providing a connecting method of optical devices capable of suppressing a periodic wavelength dependence loss and the like, due to the inter-polarization-mode interference caused when connecting a plurality of optical devices by using an optical path having a polarization-preserving characteristic, and an optical apparatus applied with the connecting method. To this end, the connecting method according to the present invention, is to connect a plurality of optical devices (11,12) to one another by using an optical path (212) of polarization-preserving type having optical characteristics in which a light is propagated along two different polarization axes for substantially equal distances. Thus, even if the polarization direction of the light input/output to/from the respective optical devices is not completely coincident with the direction of the polarization axis of the optical path, it is possible to offset the periodic wavelength dependence loss and the like caused by the inter-polarization-mode interference in the optical path, to be suppressed.
摘要翻译：本发明的目的在于提供一种能够抑制周期性波长相关损耗等的光学器件的连接方法，这是由于通过使用具有偏振光的光路连接多个光学器件时引起的偏振模式间干扰，保存特性，以及应用了连接方法的光学装置。为此，根据本发明的连接方法是通过使用具有光学特性的偏振保持型光路（212）将多个光学器件（11,12）彼此连接，其中光是沿两个不同的偏振轴传播大致相等的距离。因此，即使向各光学装置输入/输出的光的偏振方向与光路的偏振轴的方向不完全一致，也可以抵消周期性波长相关损耗等通过光路中的偏振模干涉被抑制。
