Chip-scale photonics platform with integrated wavelength-tunable laser

This technology is a photonic funnel structure for efficient and alignment-tolerant coupling of optical fiber to waveguide.

Unmet Need: Robust, efficient, and low-cost process for coupling light in and out of nanophotonic devices.

Applications: Integrated optical devices.

The small size of the chip is accomplished through chip-thinning techniques.

Integrated photovoltaic cells allow incident light on the chip to be converted into usable electrical power.

Furthermore, while wireless power delivery methods using radio-frequency and ultrasound exist, they are constrained by the device’s size and required proximity to external transducers, making such technology difficult to implement at the micron scale.

The Technology: Integrated, compact, and tunable band-interleaving.

Advantages: Highly tunable pass and stop bands.

Nevertheless, the overall bandwidth of carriers faces limitations imposed by the free spectral range, and integrating photonic components with conventional integrated circuit electronics systems continues to present a significant challenge.
