Large Beam Size Grating Coupler in Silicon‐on‐Insulator Using Fully Etched Subwavelength Gratings
Laser &Photonics Reviews, EarlyView.A fully etched, double‐period subwavelength structure is used to design a silicon‐on‐insulator grating coupler for large, well‐collimated off‐chip beams. The work experimentally demonstrates the generation of a 350‐micron wide beam, with a 54% radiation efficiency, thereby enabling efficient interaction with targets centimeters away from the chip ...

Fiber Optic Vibration Sensor Based on the Tilted Fiber Bragg Grating
Advances in Materials Science and Engineering, 2013 A temperature-insensitive fiber optic vibration sensor based on the tilted fiber Bragg grating (TFBG) is presented. The sensing head is formed by insertion of a small section of MMF between a single-mode fiber and the TFBG. The reflection light from this

Fiber Bragg Grating Based Thermometry [PDF]
NCSLI Measure J. Meas. Sci, vol 10, 4, 2015, pages 24-27, 2016 In recent years there has been considerable interest in developing photonic temperature sensors such as the Fiber Bragg gratings (FBG) as an alternative to resistance thermometry. In this study we examine the thermal response of FBGs over the temperature range of 233 K to 393 K.

High‐Speed Multimode Fiber Imaging Using Binary‐Modulated Silicon Photonics Optical Phased Array
Laser &Photonics Reviews, EarlyView.A multimode fiber imaging system at 500 frames per second is experimentally demonstrated. It is enabled by a p‐i‐n diode‐based silicon photonics optical phased array. To simplify the electrical driving of p‐i‐n diodes, a binary modulation method with a costumed‐designed digital driver circuit is proposed. Reconstruction of each frame takes only 0.1 ms,

Laser &Photonics Reviews, EarlyView.A mid‐infrared frequency‐swept source operating is presented at 50 MScans s−1 using frequency down‐conversion of time‐stretched 1.5‐µm pulses generated from an Er‐doped mode‐locked fiber laser. The developed source enables high‐resolution gas‐phase MIR spectroscopy with a bandwidth of 15 cm−1 and a resolution of 0.086 cm−1 at a measurement rate of 50 ...

All‐Fiber 2 µm Mamyshev Oscillator: Mapping of Different Operating Regimes
Laser &Photonics Reviews, EarlyView.An all‐fiber 2 µm Mamyshev oscillator is presented based on Tm‐doped fiber amplifiers separated by a broadband fixed wavelength filter and a tunable narrow bandwidth filter, which delivers 309 fs directly out of standard silica fiber. The different regimes of interaction are demonstrated, including how the mode‐locking region in terms of pump powers ...
