Claim Text:
1. An apparatus to attach a fiber block to a silicon photonics waveguide chip comprising: a planar array of polarization-maintaining optical fibers of arbitrary length; a holder base of a first length including multiple slots in parallel respectively holding partially a portion of the planar array of polarization-maintaining optical fibers, each fiber having two cores being aligned optically within corresponding slot in a direction perpendicular to the planar array; a holder cap of the first length configured to combine with the holder base for fixing the portion of the planar array of polarization-maintaining optical fibers and leaving arbitrary length of the planar array of polarization-maintaining optical fibers free beyond a first edge of the holder base but keeping only additional second length of the planar array of polarization-maintaining optical fibers free beyond a second edge of the holder base with all fiber ending facets substantially level at the second length, the second edge opposing to the first edge; a silicon photonics waveguide chip including an attachment section connected to a waveguide section, the attachment section including multiple grooves of a third length in parallel respectively aligned to multiple waveguides formed in parallel in the waveguide section, the multiple grooves being configured to respectively hold partially the second length of the planar array of polarization-maintaining optical fibers with each fiber ending facet being coupled to corresponding one of the multiple waveguides; and a lid member disposed over the attachment section to cover and fix at least partially the second length of planar array of polarization-maintaining optical fibers held in the multiple grooves.
