摘要:
A silicon photonic photodetector structure, a method for fabricating the silicon photonic photodetector structure and a method for operating a silicon photonic photodetector device that results from the photonic photodetector structure each use a strip waveguide optically coupled with a polysilicon material photodetector layer that may be contiguous with a semiconductor material slab to which is located and formed a pair of electrical contacts separated by the polysilicon material photodetector layer. Within the foregoing silicon photonic photodetector structure and related methods the polysilicon material photodetector layer includes defect states suitable for absorbing an optical signal from the strip waveguide and generating an electrical output signal using at least one of the electrical contacts when the optical signal includes a photon energy less than a band gap energy of a polysilicon material from which is comprised the polysilicon material photodetector layer.

Novel integrated electro-optic structures such as modulators and switches and methods for fabrication of the same are disclosed in a variety of embodiments. In an illustrative embodiment, a device includes a substrate with a waveguide and an optical resonator comprising polycrystalline silicon positioned on the substrate. First and second doped semiconducting regions also comprise polycrystalline silicon and are positioned proximate to the first optical resonator. The first optical resonator is communicatively coupled to the waveguide.

Various embodiments of apparatuses, systems and methods are described herein for implementing pixel-shifting or an interpixel shift to increase the effective dispersion and effective spectral resolution of a spectrometer in a manner which is faster, less complicated and more robust compared to conventional techniques that employ mechanical motion to implement pixel-shifting in a spectrometer that uses free space optical components.

An electro-optic modulator structure, a method for fabricating the electro-optic modulator structure, a method for operating an electro-optic modulator device that derives from the electro-optic modulator structure and a related communications apparatus that includes the electro-optic modulator structure all are directed towards effecting a comparatively low voltage operation of the electro-optic modulator device predicated upon consideration of optimal charge carrier injection efficiency characteristics of a PIN diode charge carrier injection based micro-ring electro-optic modulator structure as a function of applied bias voltage. To realize the foregoing result, at least in part, the PIN diode charge carrier injection based electro-optic modulator structure includes at least one of a p-doped region and an n-doped region that has a relatively high volume dopant concentration at a surface thereof.
