Abstract: A non-contact method of measuring an insertion loss of a DUT connector is disclosed. The DUT connector has a first ferrule with a first optical fiber and a first end face. The method utilizes a reference connector having a second ferrule with a second optical fiber and a second end face. The method includes: axially aligning the first and second ferrules so that the first and second end faces are confronting and spaced apart to define a gap with an axial gap distance d; measuring values of the insertion loss between the first and second optical fibers for different gap distances d>0; and estimating a value for the insertion loss for a gap distance of d=0 based on the measured values of the insertion loss when d>0.

Abstract: Methods of reshaping ferrules used in optical fiber cables assemblies are disclosed. The reshaping methods reduce a core-to-ferrule concentricity error (E), which improves coupling efficiency and optical transmission. The methods include measuring a true center of the ferrule, wherein the true center is based on an outer surface of the ferrule; and reshaping at least a portion of the ferrule to change the true center of the ferrule, wherein the reshaping includes enlarging a portion of the ferrule. A variety of reshaping techniques are also disclosed.

Abstract: Methods of reshaping ferrules (20) used in optical fiber cables assemblies (170) are disclosed. The reshaping methods reduce a core-to-ferrule concentricity error (E), which improves coupling efficiency and optical transmission. The methods include measuring a distance (δ) and angular direction (θ) from a true center (30) of the ferrule to the core (46), wherein the true center (30) is based on an outer surface (26) of the ferrule. The methods also include reshaping at least a portion (26P) of the ferrule (20) to define a new true center (30′) of the ferrule (20) and reduce the distance (δ). A variety of reshaping techniques are also disclosed.

Abstract: An optical wire bond apparatus for optically connecting an optical-electrical integrated circuit (OE-IC) to an optical-electrical printed circuit board (OE-PCB) is formed by laser writing cores in a flexible glass support member to define an array of optical waveguides. The support member has a bend section and the waveguides reside close to either a top or bottom surface of the support member at the bend section. The cores have a front-end portion that can be laser written after the front end of the support member is coarse-aligned to optical waveguide structures in the OE-PCB to obtain fine alignment. The support members can be formed from flexible glass sheets or by drawing a glass preform. A photonic assembly that includes the OE-IC and the OE-PCB optically connected using the optical wire bond apparatus is also disclosed.

Abstract: An optical interface device for optically connecting photonic devices to optical device along with methods of making. The method includes providing a glass support member that is either monolithic or laminated. A laser beam is used to write cores in the body of the support member. The support member includes a bend section and the cores generally follow the bend section and serve to define curved optical waveguides. The cores provide strong out-of-plane optical confinement, thereby allowing for strong bends and therefore a compact design for the optical interface device.
