On-chip Spectrometer Formed by a Multi-stage Structure

Status of SuperSpec: A Broadband, On-Chip Millimeter-Wave Spectrometer

SuperSpec is a novel on-chip spectrometer we are developing for multi-object, moderate resolution (R = 100− 500), large bandwidth (∼1.65:1) submillimeter and millimeter survey spectroscopy of high-redshift galaxies. The spectrometer employs a filter bank architecture, and consists of a series of half-wave resonators formed by lithographically-patterned superconducting transmission lines. The si...

Optical Measurements of SuperSpec: A Millimeter-Wave On-Chip Spectrometer

SuperSpec is a novel on-chip spectrometerwe are developing for (sub)millimeter wavelength astronomy.Our approach utilizes a filterbank ofmoderate resolution (R ∼ 500) channels, coupled to lumped element kinetic inductance detectors (KIDs), all integrated onto a single silicon chip. The channels are half-wave resonators formed by lithographically depositing segments of superconducting transmissi...

Integrated AWG Spectrometer for On-chip Optical Coherence Tomography

We present experimental results of spectral-domain optical coherence tomography systems using arrayed-waveguide gratings (AWG) for the 800-nm and 1300-nm spectral ranges. A phantom is imaged by using the 1300-nm AWG. Keywords-arrayed waveguide grating; optical coherence tomography; integrated optics
