摘要： An optical modulation device is provided by forming an optical modulation layer comprising a polymer liquid crystal having a helical structure and a non-helical structure in chiral smectic C phase. The helical structure of the polymer liquid crystal is selectively formed or removed to provide a recorded state. The recorded state is held below the glass transition point of the polymer liquid crystal. The helical pitch of the helical structure can be selectively changed to form a recorded state. The helical structure can be formed to dispose its principal axis perpendicularly to the polymer liquid crystal layer. The recorded state may be read out by detecting a reflectance from the polymer liquid crystal layer.

摘要： A method for forming an optical pattern involves subjecting a porous glass material impregnated with a photocurable composition to a patterning exposure. The composition remaining uncured in the unexposed portion of the glass material is removed from the glass material to form a pattern composed of a section containing a photocured composition filled in the pores of the glass material. The glass material is directly heated to carbonize the photocured composition present in the glass material, or heated after having been further impregnated with a substance capable of changing an optical characteristic of glass. The photocurable composition may comprise one or more members selected from an acrylic ester, a methacrylic ester, an acrylic ester resin and an epoxy resin, and optionally a photopolymerization initiator.

摘要： A chiral smectic main chain-type polymer liquid crystal includes mesogen units and a flexible chain group connecting the mesogen units having a length equal to or longer than 1,4-butylene group. The polymer liquid crystal is also characterized by having at least two units having mutually different optically active groups and having at least two recurring units which show mutually reverse helical rotations in its chiral smectic phase. Because of these features, the polymer liquid crystal can show an improved responsiveness because of its chiral smectic ferroelectricity based on an elongated helical pitch while retaining a good film-formability of a main chain-type polymer liquid crystal.
