Abstract

An optical assembly includes an optical ferrule configured to receive an input light ray through an input location on a major input surface of the optical ferrule along a first direction for coupling to an optical waveguide secured to the optical ferrule, the optical ferrule including a reference location, such that a change in a temperature of the optical assembly causes the input light ray and the input location, but not the reference location, to move respective distances d1 and d2 along a same direction along a same axis, wherein a magnitude of d1-d2 is δ, and a maximum of magnitudes of d1 and d2 is greater than 10 times δ.
