    摘要： A small Faraday rotator is placed in the inner space of a receptacle and a holder. Because the plane of polarization is rotated, even when backreflection light returns to a laser diode, the lasing state does not become unstable. Being placed in the inner space and fixed there, the Faraday rotator can be small and therefore does not increase the part cost notably. The assembly cost does not increase, because it is not required to tightly press-fit a member into a narrow hole.

    摘要： An optical receptacle that enhances the optical coupling tolerance is disclosed. The optical receptacle of the invention provides, in stead of the coupling fiber installed in a conventional optical receptacle, a glass member with a diameter substantially equal to the diameter of the external fiber. The glass member, which is held by the support, provides a convex surface that abuts against the top of the external ferrule and another surface inclined with the optical axis to prevent the light reflected thereat from returning the optical device. The glass member has a substantially homogeneous distribution in the refractive index thereof; accordingly, the fluctuation in the optical coupling with the external ferrule may be reduced.

    摘要： An optical module 11a comprises an optical-receptacle housing 13, an optical-communication subassembly 15, and a holder 17. The flange portion 13b has a plurality of first portions 13c, which extend along a reference plane perpendicular to a predetermined axis, Ax, and a plurality of second portions 13d, each of which is positioned between the first portions 13c. The outer periphery of the first portions 13c is positioned at the outside of a reference cylinder whose center is coincident with the predetermined axis Ax. The outer periphery of the second portions 13d is positioned at the inside of the reference cylinder. The optical-receptacle housing 13 and the holder 17 are temporarily fixed to each other at the second portions 13d of the flange portion 13b through second bonding members 27a to 27d. The optical-receptacle housing 13 and the holder 17 are further fixed with increased strength to each other at the first portions 13c of the flange portion 13b through first bonding members 25a to 25d. As a result, the deviation in optical alignment can be decreased to a small magnitude.
