Integrierte photonische Schaltungen für die Life Sciences

  Abstract: In einer Mehrfarben-Laser-Engine für den sichtbaren Spektralbereich konnten zahlreiche diskrete optische Komponenten durch einen integrierten Photonischen Schaltkreis ersetzt werden. Die Basis bildet eine SiN-Wellenleiterplattform. Hochwertige integrierte photonische Schaltungen (Photonic Integrated Circuits, PICs) auf SiN-Basis werden in Mehrfarben-Laser-Engines (MLEs)

Theoretical investigation of a Si RRM assisted SSB-OFDM modulator operated with a semiconductor MLL

  Abstract: Performance of a transmitter with RRM-assisted SSB-OFDM modulator and semiconductor MLL is modeled. Phase noise related penalties arise even in back-to-back configuration and significantly modify the optimum RRM bias point. Wavelength selective modulation of multiple carriers generated by

Silicon Photonics External Cavity Laser with Misalignment Tolerant Multi-mode RSOA to PIC Interface

  Abstract: There have been multiple successful implementations of hybrid external cavity lasers (ECLs) combining a reflector and delay line implemented in silicon photonics (SiP) with a reflective semiconductor optical amplifier (RSOA), motivated by wavelength tunability [1-3], and linewidth reduction [2,3]. Commonly,

Broadband couplers for hybrid silicon-chalcogenide glass photonic integrated circuits

  Abstract: We report on the design, fabrication and testing of three types of coupling structures for hybrid chalcogenide glass Ge23Sb7S70-Silicon (GeSbS-Si) photonic integrated circuit platforms. The first type is a fully etched GeSbS grating coupler defined directly in the

Broadband, temperature tolerant and passively biased resonantly enhanced Mach-Zehnder modulators

  Abstract: We describe a resonantly enhanced Mach-Zehnder modulator (MZM) that can be operated over a wide temperature range of 55°C without being actively biased, while providing a significant resonant enhancement of 6.8 at the nominal wavelength / temperature compared
