1/f noise in external-cavity InGaN diode laser at 420  nm wavelength for atomic spectroscopy
(2014-03-15)We have extensively studied the frequency noise and relative intensity noise spectra in a tunable external-cavity InGaN diode laser at blue (420 nm) wavelengths. We report flicker (1/f) frequency-noise behavior at low ... -

6 DOF repeatability measurement setup for measuring position of assembled silicon parts with nanometric resolution.
(2015-06-06)This article presents a test setup dedicated to the measurement of the 6 degrees of freedom relative positioning assembly repeatability of three micro-manufactured parts equivalent to those composing a mesoscale flexure-based ... -
9.6 GHz ultra-low phase noise signal generation from a diode-pumped solid-state laser
(2015-10)We present ultra-low phase noise microwave generation based on a photonics oscillator. By using an ultra-narrow linewidth continuous-wave laser stabilized on a high-finesse optical cavity as a frequency reference, an optical ... -
A Kerr polarization controller
(2022-01-19)Kerr-effect-induced changes of the polarization state of light are well known in pulsed laser systems. An example is nonlinear polarization rotation, which is critical to the operation of many types of mode-locked lasers. ... -
A Low-Cost USB-Compatible Electronic Stethoscope Unit for Multi-channel Lung Sound Acquisition
(2020)The diagnosis of respiratory diseases relies largely on auscultation. To further improve the diagnosis quality, continuous acoustic multi-channel surveillance of the airways is highly desirable. The application of multiple ... -
A microphotonic astrocomb
(2019-01)A microphotonic astrocomb is demonstrated via temporal dissipative Kerr solitons in photonic-chip-based silicon nitride microresonators with a precision of 25?cm?s–1 (radial velocity equivalent), useful for Earth-like ... -
A Novel Chewing Detection System Based on PPG, Audio, and Accelerometry
(2017)In the context of dietary management, accurate monitoring of eating habits is receiving increased attention. Wearable sensors, combined with the connectivity and processing of modern smart phones, can be used to robustly ... -
A novel smartphone app for blood pressure measurement: a proof-of-concept study against an arterial catheter
(2022-06-21)Smartphones may provide a highly available access to simplified hypertension screening in environments with limited health care resources. Most studies involving smartphone blood pressure (BP) apps have focused on validation ... -
A three device silicon based platform for micro-assembly and characterization.
(2016-01-06)In order to improve the assembly process of microcomponents, three high precision mechanisms were developed. All of them were designed and fabricated at CSEM, through a silicon etching process (DRIE). The devices are an ...
