Photonics' potential has changed various industries. Device and system security is important as photonics technology advances. Physical risks and photonics asset protection are examined in this work. Post-silicon device and system integrity is tested utilizing side channel signal analysis, fault injection assessment, reverse engineering, electrical and optical probing, and photonic emission analysis. Chips, imaging, probing, electrical characterization, and spectroscopy are needed for these methods. Even with breakthroughs in failure analysis and side channel measuring devices, attackers may use these systems to attack and expose critical data, cryptographic keys, firmware, c onfiguration pa sswords, an d in tellectual pr operty. Ph ysical at tacks we aken en cryption and security, giving unauthorized access to embedded system assets. All physical attacks and remedies are covered in this special issue on photonics assurance security. Photonics assurance research on limiting physical hazards and safeguarding photonics-based devices and systems is included in this special issue. Our actions will keep photonics technology safe and foster innovation across industries.

Accurate propagation loss characterization of silicon waveguides is increasingly demanded for silicon-photonics-(Si-Ph) applications with high-power continuous-wave-(CW) light sources. We report on nonlinear loss parameters of silicon wire waveguides for 1.31 μm wavelength CW light extracted from transmission data measured for different lengths and polarizations. Such parameters were, so far, unavailable, although they are required for accurately modeling Si-Ph optical circuits. More-than-ten-times enhancement of two-photon absorption from prior results for short pulse light was observed at power densities ranging up to 4.7 × 1011 W m−2 while free carrier absorption was suppressed. We estimate the nonlinear loss of the waveguides using the parameter values obtained.
