Silicon photonic two-dimensional grating couplers for C- and O-band dual-polarization coherent transceivers are analyzed with respect to their polarization splitting/combining performance. Due to scattered light in the grating's plane, a linear cross

A novel integrated sensor for the simultaneous measurement of layer refractive index and thickness based on evanescent fields is proposed. The theoretical limits for the accuracy of the sensor were examined for the example of a TiO2 layer. The influe

We present a method for the read-out of five serially arranged SOI ring resonator-based biosensors at a speed of 3 Hz/sensor and a fixed wavelength of 1550 nm. The system uses the high thermo-optical coefficient of silicon by applying AC voltages to

The scaling of nonlinear effects in multi-mode fibers with the mode count has been investigated by analytical studies and by numerical simulations. Increasing the core radius results in larger effective mode field areas, which reduces the impact of n

We investigate fundamental properties of polarization-splitting/combining 2D grating couplers for silicon photonic coherent transceivers. Linear cross-polarization related polarization crosstalk causes signal non-orthogonality. The relevance of these

Usage of multi mode SOI Waveguides including a p-i-n diode is proposed for inter-modal FWM. Devices have been designed, fabricated and characterized. An efficiency improvement of 4.2 dB is demonstrated by adding the diode and reverse bias. Crosstalk
