The abundance of acquired data from experiments and simulations makes the field of photonics a perfect environment for machine learning applications. Here we will apply Deep Neural Networks (DNNs) to predict the colour of nano-structured surfaces using either the nanoparticle geometric parameters, or laser parameters used to develop the nano-structured surfaces.

Elastic Optical Networks (EON) provide an opportunity to efficiently utilize spectrum and resources. A novel approach to implementing a survivable EON is proposed by extending current protection schemes to Network Media Channels (NMC) and incorporating Class-of-Service.

We investigate polarization singularities (C points) in the far-field of an elliptically polarized dipole. For an almost linear dipole moment, four singularities occur along directions almost aligned with the dipole moment axis - in the null intensity region. Under certain assumptions measuring two of the C points is enough to fully characterize the dipole's polarization state. We experimentally resolve these C points via weak measurement far-field polarization projection. We propose practical applications for the fundamental study of dipolar emitters in general and position sensing in particular.

Simultaneous monitoring of moisture and temperature using advanced fiber gratings is a fairly new concept. This paper implements and characterizes an apodized, 24mm long, pi-PSFBG moisture and temperature sensor through Matlab. Testing and calibration of a similar fabricated sensor records the sensitivity of 7.5+/− 0.1 pm/RH% for moisture, 10 pm/°C for temperature at a response time of 20 minutes.

Approach of laser ablation offers considerable process control to fabricate the silicon nanofibers (SNF). Ambient air oxidation converts SNF at interacting layer in to SiO2 which holds insulating characteristics.
