    Abstract: Provided are novel thio compounds and a method for preparing the same. More particularly, there is provided a novel thio compound prepared by reacting an alkylation product of p-cresol and dicyclopentadiene with mercaptan and paraformaldehyde. Unlike existing antioxidants such as 2,6-di-t-butyl-4-methylphenol (BHT) being harmful to the human body due to the high volatility, the novel thio compounds of the present invention, which have the low volatility because of their high molecular weight, give no harm to the human body. Further, with excellent performances, they are suitable to replace the existing antioxidants.

  • Patent number: 7965912
    Abstract: Two methods are presented in order to properly compensate the changes of the optical characteristics, which are caused by the optical path length change. First, a path length compensation method in which the additional optical path length, equivalent to the dicing kerf width of the substrate, is added onto the diced-to-be waveguide part of the AWG chip during the waveguide design process and fabrication process so that the compensated optical path length is maintained even after dicing. In addition, a position compensation method is provided in which an additional waveguide is added at the position shifted by a distance equivalent to the kerf width of the substrate such that the additional waveguide undergoes the minimized path length change after dicing is performed.

  • Patent number: 7912330
    Abstract: The temperature dependency of center wavelength of AWG is compensated by adjusting optical input position by cutting interface between input slab waveguide of AWG and stripe waveguide circuit connected to input slab, followed by attaching lateral sliding rod which has larger Coefficient of Thermal Expansion than chip substrate. These cut-elements are passively re-aligned on the top surface of the alignment base substrate. The cut-element of AWG main body is adhered on alignment base substrate, and the cut-element of the strip waveguide circuit connected to the input slab is attached to the lateral sliding rod. The gap between the facets of re-aligned two cut-elements is maintained by inserting thin film followed by filling gap-fill material with no flowing nature to minimize degradation of optical characteristics and maintain free lateral movement between these two cut-elements.

  • Publication number: 20080135169
    Abstract: Center wavelength of AWG is shifted due to the temperature variation. This invention described the method to compensate temperature dependency of center wavelength by adjusting optical input position passively by cutting the interface between the input slap waveguide (3) of AWG and the stripe waveguide circuit (1) connected to the input slab on a AWG chip, followed by attaching the lateral sliding rod (10) which has the larger CTE (Coefficient of Thermal Expansion) than AWG chip substrate (6). These cut-elements are passively re-aligned on the top surface of the alignment base substrate (7). At this process, the cut-element (6b) of AWG main body is firmly adhered on the alignment base substrate (7), and the cut-element (6a) of the stripe waveguide circuit (1) connected to the input slab is attached to the lateral sliding rod (10), which enables the position movement upon the temperature variation.
