Ultra-high resolution integrated arrayed waveguide spectrometer with reusable delay lines for exoplanet detection

New Integration Photonics, Inc. is proposing to developnbsp;an ultra-high resolving power (R gt; 150,000), high throughput (gt;70%)nbsp;spectrometer leveraging arrayed waveguide gratings (AWGs) on a Si3N4/SiO2 photonic integrated chip (PIC). Our groundbreaking approach introduces a reusable delay line (RDL) as a transformative alternative to the traditional multitude of waveguides. This innovation not only drastically reduces the device#39;s footprint, potentially by a factor of 1000, but also enhances chip stability and reduces the weight, power, and cost (Swap-C) . The spectrometer PIC will feature an inventive integration with a linear InGaAs detector array at the output and will incorporate fiber coupling at the input. This strategic design is meticulously crafted to yield a highly functional device housed within a butterfly package. The result is a substantial reduction in form factor (lt; 20 cmsup3;) when compared to prevailing competitors (~ 200 cmsup3;). This cutting-edge, high-resolution, and high-throughput integrated spectrometer are poised to make significant contributions, not only in applications such as the detection of exoplanets using the Precision Radial Velocity (PRV) method, but also in commercial marketsnbsp;where bulk spectrometer are currently used. The potential impact of this technology is underscored by its innovative design and promising advancements in performance, reliability and cost.
