Abstract

We report on optical components for integrated optics applications at the micro- and nanoscale. Versatile shapes and dimensions are achievable due to the liquid phase processability of SU8 resist. On the one hand, by adjusting the UV-lithography process, waveguiding structures are patterned and released from their original substrate. They can be replaced on any other substrate and also immerged in liquid wherein they still show off efficient light confinement. On the other hand, filled and hollow 1D-nanostructures are achievable by the wetting template method. By exploiting the large range of available SU8 viscosities, nanowires of diameter ranging between 50 nm and 240 nm, as well as nanotubes of controllable wall thickness are presented. Optical injection, propagation, and coupling in such nanostructures are relevant for highly integrated devices.

Abstract

International audience; Stimulated Brillouin scattering (SBS) has received much attention for decades for its numerous applications in sensors, optical amplification or design of narrow-linewidth lasers. In particular, optical fibers present Brillouin gain with a narrow bandwidth of a few tens of MHz. This permits to realize Brillouin fiber lasers (BFL) emitting Stokes lines with potential ultra-narrow linewidths. Standard architectures are based on the use of a long fiber loop in order to provide sufficient gain. The loop is then resonant for the pump requiring servo-control to lock the pump frequency to the loop resonance. Furthermore, the whole pump power may not be injected in the cavity, as the pump spectrum may be broader than the cavity resonance. Conversely, non-resonant pumping enables to fully exploit the pump power. However, as the pump-resonator detuning may drift, it suffers from mode-hopping of the Stokes wave.

Abstract

International audience; Standard laser linewidths typically range from 10 kHz for solid-state lasers up to a few MHz for semiconductors. Several techniques have been developed in the past in order to reduce lasers linewidths to sub-kHz level. It can be achieved by servo-locking the mean laser frequency to a reference frequency provided by an atomic or molecular absorption line, leading to long-term frequency stabilization. However, it does not generally offer significant reduction of short-term phase-noise. Other techniques consist in using the resonances provided by ultra-stable cavities or km-imbalanced interferometers. These methods are accurate, but are very sensitive to environmental noise which degrades the laser linewidth. Injection locking provides alternative solutions for linewidth narrowing, but the problem is merely deferred as they rely on the use of stabilized low-noise optical seeders. Besides Brillouin fiber lasers (BFL) employing the stimulated Brillouin scattering (SBS) in fibers are known to present intrinsic narrow sub-kHz linewidths [1]. We show here how the benefits of using a solidstate laser, in terms of power, and SBS, in terms of spectral purity, can be easily combined.

Abstract

International audience; We report experimental evidence of the coupling between the pump diode current and the output differential phase in a two-axis two-polarization dual-frequency solid-state laser. The effect has the same transfer function shape as that for a pump current to output power one, suggesting a pump AM/laser PM coupling in the laser medium. We report that the pump amplitude noise is negligible in the laser differential phase noise assuming a linear coupling. (C) 2016 Optical Society of America

Abstract

International audience; We propose a reliable method for stabilizing narrow linewidth Brillouin fiber lasers with non-resonant pumping. Mode-hopping is suppressed by means of a phase-locked loop that locks the pump-Stokes detuning to a local radio-frequency (RF) oscillator. Stable single-mode operation of a 110-m-long Brillouin fiber laser oscillating at 1.55 mu m is demonstrated for several hours. The beat note between two independent Stokes waves presents a phase noise level of -60 dBc/Hz at 100 Hz with a -20 dB/decade slope, and a FWHM linewidth lower than 50 Hz.

Abstract

International audience; A dual-frequency 1.55 μm laser for CW low noise microwave, millimeter and sub millimeter wave synthesis is demonstrated, where frequency stabilization is possible on each wavelength independently. The solid state Er:Yb laser output power is 7 mW. The amplitude noise is −150 dBc/Hz at 1 MHz offset frequency. In free running regime, the frequency noise is 3.10^5/f Hz/sqrt(Hz) (800 Hz on a 1μs timescale), better than commercial fibered or semi-conductor sources at this wavelength.

Abstract

International audience; A beatnote, tunable from dc to 1 THz, provided by a dual-frequency laser is used to feed an unitravelling carrier photodiode in order to produce a highly coherent THz signal radiated by a transverse-electromagnetic-horn antenna. The THz signal is detected and analyzed by a subharmonic mixer coupled to an electrical spectrum analyzer. All components involved in this experiment operate at room temperature without phase locking the beatnote. So far, the dynamic range evolves from 58 dB at 282 GHz to 15 dB at 1.026 THz, and the measured linewidth is better than 30$~$ kHz. Linewidth narrowing using a Brillouin fiber laser pumped by the dual-frequency laser leads to a beatnote of 500-Hz linewidth at 1$~$THz.

Abstract

International audience; This Letter describes the design of an optical amplifier system optimized to reduce the relative intensity noise (RIN) of the input signal, and discloses its performance in terms of intensity noise reduction and bandwidth, without phase noise degradation. This polarization-maintaining amplifier is composed of an erbium-doped fiber amplifier (EDFA) cascaded with a semiconductor optical amplifier (SOA). The EDFA is sized to feed the SOA with a constant power corresponding to the optimal saturation level for noise reduction, through coherent population oscillations. When properly optimized, such an amplifier provides, simultaneously, 17 dB optical gain, 5.4 dB noise factor, and 20 dB reduction of the input-RIN across a 3 GHz bandwidth, without any electronics feedback loop.
