Optopax engineers precise free-space optical pathways that control beam shape, wavefront quality, and alignment into PIC interfaces. We support designs with dense optical I/O, vertical grating couplers, and massively parallel optical channels while targeting low loss, high stability, and manufacturability at scale.

We design and integrate micro-lens arrays, DOEs, and metasurfaces that route and shape light with high precision. These elements enable dense fan-out, controlled mode shaping, and efficient coupling with PICs or emitter arrays, supporting compact, scalable optical-compute and interconnect architectures.

Optopax has in-house modelling tools and expertise for near-field electric field propagation at optical–PIC boundaries. We simulate source fields, grating coupler in-coupling, and waveguide interactions, ensuring that free-space and micro-optic elements deliver maximum performance in combination with customer PIC structures.

We develop mechanically stable, thermally aware packaging architectures compatible with sub-micron active alignment. Our designs ensure robust integration of optics, PICs, detectors, DOE and metasurface components—maintaining optical stability under vibration, temperature variation, and high-density assembly constraints.

Optopax aligns and integrates custom optical pathways with customer-defined lasers, detectors, PIC ports, and metasurface interfaces. We optimize physical placement, coupling geometry, and tolerance budgets to ensure minimal loss, high repeatability, and seamless mechanical and thermal compatibility.

We create complete metrology strategies for optical-compute modules, including wavefront analysis, near-field/far-field characterization, alignment verification, and thermal drift testing. Optopax defines calibration workflows to ensure each module performs consistently across manufacturing runs and environmental conditions.
