Phase Modulators – optical modulator - RP Photonics
Using KTP, RTP and LiNbO 3 crystals, ALPHALAS offers phase modulators for various applications like active mode locking, side-frequency generation and laser resonator cavity control. In addition to the standard products designed for 1064 nm, other customer-specific wavelengths can be offered as well. Here you can submit questions and comments.
Electro-optic Modulators – EOM, Pockels cells, phase modulator ...
The simplest type of electro-optic modulator is a phase modulator containing only a Pockels cell, where an electric field (applied to the crystal via electrodes) changes the phase delay of a laser beam sent through the crystal.
Self-phase Modulation – SPM, Kerr effect, carrier density - RP …
Self-phase modulation is the nonlinear phase modulation of a beam, caused by its own intensity via the Kerr effect.
Electro-optic modulator - Wikipedia
Phase modulation (PM) is a modulation pattern that encodes information as variations in the instantaneous phase of a carrier wave. The phase of a carrier signal is modulated to follow the changing voltage level (amplitude) of modulation signal.
An Integrated Low-Voltage Broadband Lithium Niobate Phase Modulator ...
Here, we demonstrate an integrated phase modulator, based on a thin-film lithium niobite platform, which simultaneously features small on-chip loss (~1 dB) and low half-wave voltage over a large spectral range (3.5–4.5 V at 5–40 GHz).
Phase-modulating lasers toward on-chip integration
2016年7月26日 · Here, we demonstrate the operation of phase-modulating lasers that emit arbitrarily configurable beam patterns without requiring any optical elements or scanning devices. We introduce a...
Here we demonstrate a dual channel phase modulator using a thin-film LNOI platform with low on-chip optical loss ( 1 dB/channel) and low RF V (4.5 V at 40 GHz) that is relatively constant (less than 28% variation) over wide frequency range (from 5 to 40 GHz).
Non-resonant recirculating light phase modulator - AIP Publishing
2022年10月4日 · In this paper, we propose, theoretically investigate, and experimentally demonstrate a recirculating phase modulator, which increases the modulation efficiency by modulating the optical field several times in a non-resonant waveguide structure.
Intensity Modulators - RP Photonics
The MXER-LN series of intensity modulators is a family of high-performance modulators exhibiting a superior extinction ratio. These modulators are available for the C and O bands and find interest for Distributed Temperature Sensing (DTS) and Quantum Key Distribution (QKD) .
Robust, efficient, micrometre-scale phase modulators at visible ...
2021年11月22日 · Here, we demonstrate visible-spectrum silicon nitride thermo-optic phase modulators based on adiabatic micro-ring resonators that offer at least a one-order-of-magnitude reduction in both the...
