Recently, the authors have demonstrated large-scale integrated systems with several million transistors and hundreds of photonic elements. Yielding such large-scale integrated systems requires a design-for-manufacture rigour that is embodied in the 10 000 to 50 000 design rules that these designs must comply within advanced complementary metal-oxide semiconductor manufacturing. Here, the author...

Two structures are analyzed with numerical modeling as candidates for perpendicular coupling of optical signals from a dielectric waveguide to a photonic bandgap (PBG) waveguide. The first consists of a perfectly electric conducting (PEC) grating and PBG mirror to couple power out of the dielectric waveguide, along with a circular-like lens to couple that power into the PBG waveguide. The secon...

We show that the properties of the confined modes of a photonic band-gap ~PBG! waveguide can be calculated with good accuracy by replacing it with an effective corrugated waveguide that represents only the structure in the vicinity of the middle slab. Such a replacement is helpful in the design of the PBG waveguides as well as in the understanding and analysis of the coupling of different waveg...

We present a novel broadband microwave photonic phase shifter based on a single III-V microdisk resonator heterogeneously integrated on a silicon-on-insulator waveguide. Fully 2π phase shift tunability is accomplished by free-carrierinduced effective index modulation.

Chip-based photonic quantum computing is an emerging technology that promises much speedup over conventional computers at small integration volumes. Particular interest is thereby given to polarisation-encoded photonic qubits, and many protocols have been developed for this encoding. However, arbitrary wave plate operation on chip are not available so far, preventing from the implementation of ...

Monolithic integration of photonic crystal lasers and waveguides is proposed using quantum well intermixing. Coupling between a double-heterostructure nanocavity and a regular single-line-defect waveguide is optimized to have a high coupling efficiency (93%) and a high quality factor (6.8× 103) without fine-tuning of the lattice. The design is completed with a waveguide exit of robust direction...

Waveguide nonlinear-optic devices and integrated semiconductor lasers with appropriate design can perform quantum-optics functions that are potentially useful for R&D of quantum information processing. This paper reports the current status of the work of the authors group in this new subarea "Quantum Photonic Devices", including theoretical background, design and fabrication of quasi-phase matc...
