We report on the modulation responses of an injection-locked vertical-cavity surface-emitting laser (VCSEL) measured using optical spin-polarization technique. reveal that weak injection locking is suitable to maintain a strong resonance response at high-frequency region depending linear birefringence VCSEL, unique feature response. The results can be reasonably reproduced with simulated ones b...

Dynamics of nuclear spin decoherence and nuclear spin flip-flops in self-assembled InGaAs/GaAs quantum dots are studied experimentally using optically detected nuclear magnetic resonance (NMR). Nuclear spin-echo decay times are found to be in the range 1-4 ms. This is a factor of ~3 longer than in strain-free GaAs/AlGaAs structures and is shown to result from strain-induced quadrupolar effects ...

AIM Photonics has developed a high precision laser attach process using an ultra-precise ASM Amicra NANO 300 mm die-to-wafer flip-chip bonder and integrated solder stamping system. Laser die are placed with accuracy (<1 µm) soldered to form AuSn eutectic bond. This photonic platform low optical losses, SiN waveguides measuring on the order of 0.4 dB/cm calculated laser-to-waveguide coupling ...

Cellular FLIP (c-FLIP) specifically inhibits caspase-8 and suppresses death receptor-induced apoptosis. c-FLIP has also been reported to transmit activation signals. In this study, we report a novel function of c-FLIP involving inhibition of myeloid cell activation through antagonizing the selective innate signaling pathway. We found that conditional knockout of c-FLIP in dendritic cells (DCs) ...

The design of a biwavelength transceiver (TRx) module for parallel simultaneous bidirectional optical interconnects is described. The TRx module has been implemented using two different wavelengths, 850 and 1060 nm, to send and receive signals simultaneously through a common optical interface while optimizing cost and performance. Filtering mirrors are formed in the optical fibers which are emb...

We show that a significant quantum gain corresponding to squeezed or over-squeezed spin states can be obtained in multiparameter estimation by measuring the Hadamard coefficients of 1D 2D signal. The physical platform we consider consists two-level atoms an optical lattice squeezed-Mott configuration, more generally correlated spins distributed spatially separated modes. Our protocol requires p...
