Abstract
An optical fiber array includes a pair of blocks having respective recesses which, when the blocks are combined together, cooperate together to define a cavity, and a plurality of optical fibers having respective end portions accommodated within the cavity in a linear array. Neighboring end faces of the blocks adjacent end faces of the optical fibers are ground at an inclination relative to a common plane in which the linear array of the end portions of the optical fibers lie and also relative to an optical axis of each of the optical fibers. A method of making the optical fiber array and a wavelength selecting device utilizing the optical fiber array are also disclosed.
