摘要： In an integrated optical receiver or transmitter, both the displacement of an optical axis caused by thermal changes and the property degradation of an optical functional circuit are inhibited. A planar lightwave circuit having a substrate and a waveguide-type optical functional circuit formed thereon composed of a material different from that of the substrate, and includes a waveguide region formed only of an optical wavelength that is in contact with a side forming an emission-end face of the optical waveguide for propagating the light emitted from the optical functional circuit or an incident-end face of an optical waveguide for propagating the light incident on the optical functional circuit. The planar lightwave circuit is fixed to a fixing mount only at the bottom of the substrate where the waveguide region is formed.

摘要： 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.
摘要翻译：常规的光信号处理装置具有分光元件的分光特性的温度依赖性导致性能下降的缺点。为了解决温度依赖性，已经有一种形成用于在AWG的阵列波导上分割芯的多个凹槽的方法。然而，这种方法不能避免过多的损失，导致制造成本高。通过直接控制由空间光调制器的元件装置形成的调制特性曲线，可以以更简单和低成本的方式实现无热化。因此，光信号处理装置的空间光学系统中的光耦合损耗显着降低。可以实现更精确的温度补偿，以应对器件对温度波动的实际行为，包括导致光学系统的复杂温度波动的因素。

摘要： Conventionally, there has been a problem that a structure in which optical signals outputting from a substrate facet in a PLC are optically coupled to a different bulk type optical device is so complicated that its assembly is laborious. There also has been a problem that a structure in which an output facet of a PLC is polished with an angle results in an increase in coupling loss in free space optics. With a lens bonded to an angled facet of a PLC, an optical circuit of the present invention achieves an optical coupling, with low loss, to a bulk-type optical device or another PLC with a simple structure. Moreover, a lens part and an optical fiber part are respectively bonded to different core apertures exposed on a single angled facet. Thereby, optical signals can be inputted to and outputted from the PLC through the single facet.

摘要： 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.

摘要： An object of the present invention is to provide a wavelength blocker having the function of adjusting or cutting off the light intensity of a wavelength division multiplexed (WDM) optical signal of a given wavelength. 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.
