Workshop Integrated Photonics
Over the last 20 years, femtosecond lasers have transformed many areas in science and technology such as femtosecond time-resolved spectroscopy, laser micromachining, fast optical and electrical signal processing, and ultra-high precision signal sources for the upcoming quantum technologies. In addition, they have enabled octave-spanning optical frequency combs, a Nobel Prize-winning technology, enabling phase-coherently linking of optical and radio frequencies with a precision limited only by the definition of time itself. Nevertheless, today’s ultra-fast lasers are too big, too expensive, and prone to fail for many applications.
Creating low-noise CMOS compatible femtosecond lasers, that can be cointegrated with electronics is becoming critical for exploiting the reduced power consumption, high bandwidth, low timing jitter and most importantly guaranteeing all this at a lower cost. This workshop provides opportunities to exchange ideas and discuss the latest technologies in this field and stimulate new ideas for future technology development.
FEMTOCHIP is an EU-funded Research & Development project to realize an optically pumped femtosecond laser on a single microchip with performance comparable to state-of-the-art table-top laser systems. This effort necessitates and combines several key breakthrough results across the domains of laser physics, material science and micro-technology, that we are targeting to achieve within this project. We believe that, if successful, this project will lay the foundation for making low-noise femtosecond laser technology accessible at a 1% fraction of the current cost to a wide range of users in science and industry in the long-term.
The on-chip architecture will permit achieving form-factors, power efficiency and robustness compatible with modern micro-electronic systems, laying the foundation for ubiquitous use e.g. in point-of-care diagnostics, security inspections, handheld precision navigation devices and pervasive multi-platform environmental sensing. In addition, the scaling ability of on-chip technology opens unprecedented opportunities for information processing, e.g. by pushing the resolution in analogue-to-digital conversion (ADC) potentially by at least three orders of magnitudes.
