Abstract
Apparatus couples optical fiber to an optoelectronic component with a collet, a cylindrical member, a connector, and hermetically sealing means. The collet has a central orifice through a knurled end portion, a central portion with a male thread, and a second end portion formed with a slotted cone sleeve. The cylindrical member has opposed centrosymmetric recesses that meet, forming a small axially oriented aperture. One recess is formed with an axial female thread, with a conical indentation terminating at the aperture. The female thread can to engage with the collet male thread. Thread engagement of member and collet results in engagement of the member at the conical indentation with the coned sleeve, drawing the slotted sides inwardly, firmly gripping the collet held optical fiber. The other recess has a second axial female thread from the opposite end of the member toward the aperture. The member has a radially directed sight hole. The connector couples the optoelectronic component to an electronic circuit. Its peripheral surface has a second male thread to engage with the second female thread of the member. Orientation of the collet held fiber with respect to the optoelectronic component can be varied by adjusting the second threads, with observation through the sight hole.
