Integrated polarizing devices based on tilted gratings in silicate waveguides
Photonic integrated polarizers are of interest in systems where the fidelity of the polarization state is crucial, such as coherent communications, quantum information processing and high-performance sensing. This talk will explore novel schemes towards the integration of polarization devices based on integrated tilted gratings in silicate waveguides. Dr. Posner will present methods for the design and fabrication of 45° tilted gratings for use as polarisers [1] and polarising couplers [2] at wavelengths of operation in the telecommunications C-band (1530-1570 nm). The devices’ performance will be described, with details provided on techniques for characterizing polarization extinction ratio and the broad spectral bandwidth. Future directions of investigation will be discussed.

Dr Matthew T. Posner of Excelitas Technologies
Biography:
Dr. Matthew T. Posner obtained an MEng in Electronics Engineering from the University of Southampton in 2013 and a PhD from the Optoelectronics Research Centre, University of Southampton in 2017. Today he is a Process Scientist in silicon-based photodetectors at Excelitas Technologies, Montreal, QC, Canada. His professional interests relate to microfabrication techniques for the development of photonics components. Dr. Posner is a member of the OSA, SPIE and IEEE Photonics Society, through which he supports programs for industry engagement, student and early career professional development, as well as outreach education and public engagement initiatives. He has received awards for his endeavours, with the most notable featuring the 2017 University of Southampton Student Union’s Award for Best Contribution to a Society and the 2015 South East England Physics Network Public Engagement Innovation Award.
