DESCRIPTION:Jens Hofrichter\, PhD\,\nLead engineer optics and photonics\nS
 piden AG\nAbstract\nIn this talk we will discuss several photonic and opti
 cal products based on optical filtering. We will review the fundamental ph
 ysics of filtering\, basic building blocks and the existing technological 
 implementations. An outlook is given towards future products. Open challen
 ges and issues are highlighted that require >>YOUR<< future research.\n\nB
 io\nJens Hofrichter\, PhD\, has 15 years of experience in integrated photo
 nics R&D. He drove the development of the passive components\, wafer-level
  test infrastructure [2] and monolithic laser integration of silicon photo
 nics at IBM resulting in the 100G LR4 transceiver [3\,4\,6]. In 2015 he mo
 ved to ams AG\, where he was setting up the fully automated optical produc
 t validation and optical wafer-level testing capabilities for medical and 
 specialty products. He was in charge of the radiation hard monolithic phot
 odiode development\, which led to the development of the AS5950/AS5951 pro
 duct family used in 16 and 32 slice computed tomography (CT) scanners [7\,
 8]. He was leading the hybrid bonding development project resulting the wo
 rld’s first non-Cu hybrid bonded imager [5]. After that\, he was leading
  the cross-divisional camera team for the development of miniature cameras
  for AR applications. As co-inventor of the optical microphone\, he appoin
 ted program manager of the related industrialization program in the ams-Os
 ram group. In 2022 he moved to Spiden AG\, where he is currently leading t
 he optical and photonic integration activities for next-gen medical sensor
 s. He is the (co)author of more than 30 patent families mainly in the fiel
 d of photonic integration and imaging sensors and does not care about his 
 H-factor\, but bringing products to market and happy customers.\nHe holds 
 a MSc degree in Electrical Engineering from RWTH Aachen for the world’s 
 CMOS compatible synthesis method of graphene [1]. In 2013 he was awarded a
  PhD in Photonics from TU Eindhoven University of technology for the work 
 on InP microdisk lasers. In 2021 he obtained the PMP project manager certi
 fication from the Project Management Institute (PMI).\n \nSelected public
