摘要： A method of manufacturing a polarizing glass sheet includes subjecting, while heating, a glass preform sheet containing metal halide particles to down-drawing, to thereby provide a glass member having stretched metal halide particles dispersed in an aligned manner in a glass matrix, and subjecting the glass member to reduction treatment to reduce the stretched metal halide particles, to thereby provide a polarizing glass sheet. A shape of the glass preform sheet during the down-drawing satisfies a relationship of the following expression: L1/W1≥1.0 where L1 represents a length between a portion in which a width of the glass preform sheet has changed to 0.8 times an original width and a portion in which the width of the glass preform sheet has changed to 0.2 times the original width W0, and W1 represents a length equivalent to 0.5 times the original width W0 of the glass preform sheet.

摘要： What is achieved is an optical wavelength multiplexer/demultiplexer not necessarily requiring the function of adjusting the optical path. A value (ΔLmax−ΔLmin)/L obtained by dividing a difference between a maximum value ΔLmax and a minimum value ΔLmin of ΔL in a range of −40° C. to 80° C. by L is 8×10−6 or less where L represents a length of a crystallized glass (1) at 30° C. and ΔL represents a difference between a length (Lt) of the crystallized glass (1) at each of the temperatures and the length (L) thereof at 30° C.
