SiPh = The process technology used to manufacture photonic devices
Optical chip = The actual chip (PIC) made using SiPh
Optical engine = The fully integrated optical subsystem that includes lasers and interfaces, ready for direct use
- OpenLight recruits experienced SiPh talent from GlobalFoundries, signaling continued focus on silicon photonics execution
- Addition of semiconductor industry veteran suggests scaling toward manufacturing and commercialization phase
> OpenLight is strengthening its executive bench with proven SiPh talent and semiconductor manufacturing expertise, suggesting the company is transitioning from development toward production readiness and market deployment.
Staff at the Ram temple in Ayodhya have been accused of siphoning donations from devotees. We explain how the scandal could mean more trouble for the Indian government
- $FORM officially introduced the Pharos™ Optical Probe Series on September 23 for SiPh and CPO testing.
- Pharos supports both edge coupling and surface/grating coupling using FAUs with micro-optics tailored to the DUT.
- The key is not just optical coupling, but the combination of low-loss coupling, precise alignment, automated calibration, and repeatability in a single probe family.
- The family includes short and long configurations for both edge and surface coupling, including applications such as beam expanders and CPO interfaces.
- Pharos integrates with $FORM’s SiPh-Tools 4.0 AutoCal and automated alignment workflow and is compatible with TRITON, CM300xi-SiPh, and SUMMIT200 platforms.
> The bigger point is that $FORM is expanding beyond the probe station itself and moving further into the optical interface layer of the SiPh/CPO test stack.
> As CPO moves toward HVM, repeatable wafer-level optical alignment and coupling could become a major test bottleneck, and Pharos directly targets that layer.
> With TRITON positioned at ECOC 2026 as a production-ready SiPh test cell and Pharos now extending into optical probing, $FORM’s strategy to capture more of the wafer-level SiPh test stack is becoming increasingly clear.
Deutsche Bank's former head of private banking confessed in court that he siphoned off more than €626,000 ($729,950) from rich clients in multiple installments over a period of one-and-a-half years
