Optical Isolators for Photonic Integrated Circuits
With the advance of mature fabrication technologies, photonic integrated circuits (PICs) reach ever-higher levels of complexity. Integration of thousands of components has been shown [1], with each main technology showing an exponential growth in complexity [2]. This increase in complexity requires a convergence in technologies, and the roadmaps are currently being pushed by silicon nitride, (h...
متن کاملPhotonic Integrated Circuits for Optical Logic Applications
The optical logic unit cell is the photonic analog to transistor-transistor logic in electronic devices. Active devices such as InP-based semiconductor optical amplifiers (SOA) emitting at 1550 nm are vertically integrated with passive waveguides using the asymmetric twin waveguide technique and the SOAs are placed in a Mach-Zehnder interferometer (MZI) configuration. By sending in high-intensi...
متن کاملAll-silicon optical contactless testing of integrated circuits
A novel approach for replacing mechanical probes used for wafer level testing with an optical contactless method for the application and extraction of test vectors from advanced silicon integrated circuits (ICs) is described. Experimental results demonstrate its feasibility, using a novel silicon light-emitting diode (LED) and silicon light sensors fabricated on the IC. The proposed method uses...
متن کاملReverse Engineering Camouflaged Sequential Integrated Circuits Without Scan Access
Integrated circuit (IC) camouflaging is a promising technique to protect the design of a chip from reverse engineering. However, recent work has shown that even camouflaged ICs can be reverse engineered from the observed input/output behaviour of a chip using SAT solvers. However, these so-called SAT attacks have so far targeted only camouflaged combinational circuits. For camouflaged sequentia...
متن کاملReverse Engineering Integrated Circuits Using Finite State Machine Analysis
Due to the lack of a secure supply chain, it is not possible to fully trust the integrity of electronic devices. Current methods of verifying integrated circuits are either destructive or non-specific. Here we expand upon prior work, in which we proposed a novel method of reverse engineering the finite state machines that integrated circuits are built upon in a non-destructive and highly specif...
