摘要： An optical device comprises a first refractive index distribution (RID) type lens, having one end face ground diagonally, first and second ports connected to the diagonally ground end face, an optical functional element connected to another end face of the first RID type lens, a second RID type lens, having one end face ground diagonally, and another end face placed so as to face the end face of the first RID type lens through the optical functional element, and a third port connected to the diagonally ground end face. An optical path from the first port reflected by the optical functional element to the second port, wherein the optical path length of the reflected light through the first RID type lens is equal to an optical path length of transmitted light from the first port through the optical functional element through the second RID type lens to the third port.

摘要： In the manufacture of an arrayed waveguide grating type optical multiplexer/demultiplexer, respective slab waveguides are provided at input sides and output sides of a waveguide array in a cladding layer formed upon a substrate, which includes plural waveguides whose lengths differ and which are arranged in parallel; and an input waveguide is provided at the input side of the input side slab waveguide, while plural output waveguides are provided at the output side of the output side slab waveguide. The waveguides are made from a material for which the difference between the effective refractive indices for the two polarizations is large, and thereby, when multiplexed light which consists of plural lights of different wavelengths is inputted to said input waveguide, lights which have been separated by wavelength and by polarization are outputted from each of said output waveguides. As a result, it is possible to make a polarization/wavelength multiplex transmission circuit using fewer elements.

摘要： A collimator lens having a low reflectivity and significantly improved durability against high-power light is provided so that optical parts using the collimator lens can be reduced in size and cost lowered. A plurality of optical fibers can be connected to the collimator lens to produce a variety of fiber collimators and optical parts based on the fiber collimator. The collimator lens is made essentially of quarts glass whose refractive index is graded radially so as to increase towards the optical axis and decrease gradually towards the outer periphery. The collimator lens and optical fibers are connected directly by fusion.
