  • Pharos Probe

The Pharos™ Optical Probe Series is a next-generation family ofoptical probes designed for silicon photonics testing in high-volume manufacturing environments. Pharos optical probes provide low-loss optical coupling for both edge-coupling and surface-coupling applications. Each Pharos optical probe consists of a fiber array unit (FAU) with micro-optics tailored to ideally match the customer’s device under test (DUT).

Designed for applications in AI, data centers, wearables, and other silicon photonics markets, Pharos optical probes provide accurate and reliable testing of optical transceivers, sensors, co-packaged optics (CPO), and other photonic devices.

Paired with FormFactor’s Autonomous Silicon Photonics Assistant, the Pharos Optical Probes enable automated calibration and alignment and allow users of all experience levels to perform complex optical test measurements with ease.

Pharos optical probes are compatible with FormFactor’s TRITON™, CM300xi-SiPh, and SUMMIT200 probe stations, delivering consistent, low-loss coupling and faster time-to-insight for your silicon photonics testing needs.

  • Three Versatile Versions:
    • Short Lens: Perfect for wafer level trenches with shorter trench depths and working distances.
    • Long Lens: Designed for wafer level V-grooves with deeper trenches and longer working distances.
    • Vertical Version: Optimized for vertical/grating coupler coupling applications, offering versatility across this wafer-level photonics technique.
  • Low-Loss Edge Coupling:
    The Pharos-Edge™ Short and Long Lens ensures low-loss coupling for wafer-level trenches and V-grooves, providing high-precision optical measurements that are crucial for Silicon Photonics testing.
  • Automated Calibration with AutoCal:
    Integrated with SiPh-Tools 4.0, the AutoCal feature simplifies the calibration process, offering faster setup and reducing the need for manual adjustments. This results in improved throughput and lower operational costs.
  • Patented Fiducial and Lens Technology:
    FormFactor’s unique optical fiducial and lens design provide accurate positioning and reliable results with minimal user interaction, ensuring repeatable and precise measurements.
