The wavelength blocker provided by the present invention has the following features. Specifically, the wavelength blocker has a structure configured to cut off light of any diffraction order other than required diffraction order, contained in an optical signal diffracted by an arrayed waveguide grating that demultiplexes a wavelength, and thus, the wavelength blocker has crosstalk characteristics or an extinction ratio superior to those of a conventional wavelength blocker and thus has optimum packaging design. Further, the wavelength blocker can become smaller in size than the conventional wavelength blocker, and enables achieving polarization independence and cost reduction. | 01-28-2010 |
20100183310 | DISPERSION COMPENSATOR - Conventional dispersion compensators were not sufficient to satisfy a demand to set a different dispersion value for each WDM wavelength in a ring-mesh type network that utilizes wavelength selective switches or the like. The devices were insufficiently reduced in size and power consumption and used with difficulty to change dispersion characteristics for each wavelength flexibly in a simple manner. A dispersion compensator of the present invention uses general-purpose optical components including a spatial light modulator for providing discrete phases to set appropriately the relationship between the focusing beam radius and the spatial light modulator pixel, thereby providing various dispersion compensation characteristics. Attention is focused on the correspondence between multiple pixels on the spatial light modulator providing discrete phases and a communication channel band, thereby allowing for changing the flexible dispersion characteristics and realizing the setting of an independent dispersion value for each WDM wavelength. | 07-22-2010 |
20100316385 | OPTICAL SIGNAL PROCESSING DEVICE - A conventional optical signal processing device had a disadvantage where the temperature dependency of the spectroscopic characteristics of a spectroscopic element causes a deteriorated performance. In order to solve the temperature dependency, there has been a method to form a plurality of grooves for dividing a core on the array waveguide of the AWG. However, this method cannot avoid an excess loss and causes a high manufacture cost. By directly controlling the modulation characteristic profile formed by an element device of a spatial light modulator, athermalization can be achieved in a simpler and low-cost manner. This consequently provides a remarkable reduction of the light coupling loss in the spatial optical system of the optical signal processing device. More accurate temperature compensation can be realized that copes with an actual behavior of the device to a temperature fluctuation, including causing factors of a complicated temperature fluctuation of the optical system. | 12-16-2010 |
20110228374 | OPTICAL SIGNAL PROCESSING DEVICE - In a conventional optical signal processing device, a confocal optical system is configured in which a focusing lens is positioned at a substantially-intermediate point of a free space optical path. Thus, the free space optical system had a long length. It has been difficult to reduce the size of the entire device. The optical signal processing device of the present invention uses a lens layout configuration different from the confocal optical system to thereby significantly reduce the length of the system. The optical signal processing device consists of the first focusing lens positioned in the close vicinity of a signal processing device, and the second focusing lens positioned in the vicinity of a dispersing element. A distance between the dispersing element and the signal processing device is approximately a focal length of the first focusing lens. Compared with the conventional technique, the length of the optical path can be halved. | 09-22-2011 |
