Precision-machined substrates, fused silica capillaries, and flow configurations ready for optical transceiver packaging and industrial laser arrays.
Optical Fiber V-Grooves (V-Groove Arrays) serve as the fundamental mechanical alignment foundation for multi-channel optoelectronic interconnects, arrayed waveguide gratings (AWG), and Co-Packaged Optics (CPO). Fabricated primarily from high-purity fused silica (JGS1), Borofloat 33®, and single-crystal silicon, these high-aspect microstructures must maintain sub-micron geometric tolerances across critical thermal gradients.
Core-to-core pitch consistency (typically 127 µm or 250 µm) is maintained within ±0.3 µm cumulative error across up to 128 channels. This precision mitigates severe insertion losses during edge-coupling and vertical grating coupling in transceiver modules.
Anisotropic etching along single-crystal silicon planes (typically 54.74° for (100) silicon) or diamond micro-grinding on fused silica achieves an angular tolerance of ±0.1°. This ensures identical seated heights (eccentricity <0.5 µm) for bare fibers.
By pairing high-purity synthetic fused quartz (CTE: 0.5×10⁻⁶/K) or Borofloat® with matched quartz cover lids, thermo-optic expansion mismatches are eliminated, preventing adhesive delamination and fiber pistoning during -40°C to +85°C Telcordia cycling.

As global data architectures pivot toward 1.6T and 3.2T optical transceivers, standard optical alignment components must evolve beyond basic single-row topologies.
Transitioning from planar 1D arrays to high-density 2D stacking configurations (e.g., 2×16, 4×32), allowing over 128 fibers per connector interface to facilitate dense co-packaged optics (CPO) architectures.
Direct integration of precision refractive microlens arrays (MLA) on the front-facet of the quartz V-groove lid. This enables collimated or focused beam mode-field matching directly into silicon PIC waveguides without active discrete alignment.
