Near infrared integrated photonic switches for portable quantum sensors
نویسندگان
چکیده
A novel integrated semiconductor photonic switch, based on carrier-induced refractive index changes, has been designed and fabricated for use at near infrared wavelengths (890-920 nm, 750-780 nm 745-775 nm). These switches are intended in quantum sensors which rely the spectroscopy of caesium, rubidium or potassium atoms respectively. The beam-steering properties 890-920 device presented its extinction ratio measured to be 13.4 dB. This measurement was limited by coupling efficiency. Subsequent changes made testing equipment include implementation an automated routine. new experimental setup will facilitate full characterisation newly optical switches, operation wavelength ranges

Textile integrated sensors and actuators for near-infrared spectroscopy.
Being the closest layer to our body, textiles provide an ideal platform for integrating sensors and actuators to monitor physiological signals. We used a woven textile to integrate photodiodes and light emitting diodes. LEDs and photodiodes enable near-infrared spectroscopy (NIRS) systems to monitor arterial oxygen saturation and oxygenated and deoxygenated hemoglobin in human tissue. Photodiod...

متن کاملIntegrated photonic switches for nanosecond packet-switched optical wavelength conversion.
We present a multifunctional photonic switch that monolithically integrates an InGaAsP/InP quantum well electroabsorption modulator and an InGaAs photodiode as a part of an on-chip, InP optoelectronic circuit. The optical multifunctionality of the switch offers many configurations to allow for different optical network functions on a single chip. Here we experimentally demonstrate GHz-range opt...
