“…Figure 2 shows histograms of the local birefringence obtained from numerical simulation and from the method described in section 2. It appears that the distribution of the calculated local birefringence is close to a Rayleigh one, which agrees with the model adopted in [6,7]. …”

more, the ICPA has a much shorter distance to the radio-frequency output of the wireless transceiver than a conventional antenna. This implies a smaller transmission loss, which can be translated as an enhancement to the ICPA radiation efficiency by a few percent. CONCLUSIONThe prototype ICPA, printed on a 28-pin dual-in-line integratedcircuit-pressed ceramic package, has been fully studied from the antenna viewpoint for the single-chip solutions of wireless transceivers at the 2.4-GHz band using deep submicron COMS technology. The fabrication of the ICPA is compatible with standard integrated-circuit-pressed ceramic-package technology. It has been demonstrated that CMOS chip loading greatly increases the impedance bandwidth, but slightly decreases the radiation efficiency of the ICPA. The loaded ICPA achieved impedance bandwidth of 15.7%, radiation efficiency of 64 Ϯ 4%, and gain of Ϫ2.0 dBi. These performance parameters of the ICPA are sufficient for Bluetooth and many other applications.This novel ICPA has opened up many opportunities for further research and development. Firstly and most importantly, the ICPA should also be studied from the circuit viewpoint in order to understand the effect of the ICPA on the signal integrity of the single-chip wireless transceivers. This is believed to be quite a challenging work and has received our utmost attention. Secondly, as the surface-mount integrated-circuit ceramic-ball grid-array package is usually chosen for the single-chip solutions of wireless transceivers, the performances of the ICPA implemented on this type package are certainly worthy of investigation. Thirdly, printed antenna candidates with better efficiency should be developed for ICPA applications. Finally, the codesign tool of CMOS integrated circuits-the ceramic package-and the antenna should be made available for the successful realization of single-chip wireless transceivers.

“…Therefore, we can think of a few limiting factors preventing further improvement of the spatial resolution: 1) the onset of spontaneous Brillouin scattering from the FWM-pump power that results in FWM-pump depletion and a large amount of noise; 2) the gradual polarization misalignment of the FWM-pump waves due to the residual birefringence in the fiber for larger ∆λ, giving rise to a decrease of the FWM efficiency; 3) the MI that depletes and limits the amplitude of the Brillouin-pump pulse. In general, all these effects are stronger in the case of a DSF than a standard fiber, mainly due to its smaller effective area, smaller chromatic dispersion, and larger residual birefringence [9], [10]. These aspects are clearly seen in our result, where the spatial resolution in the DSF is several times larger than the case of standard fibers.…”

We analytically derive a decoherence model for orbital angular momentum states of a photon in a multimode optical fiber and show that rate of decoherence scales exponentially with l 2 , where l is the azimuthal mode order. We also show numerically that for large values of l the orbital angular momentum photon state completely dephases. However for lower values of l the decoherence can be minimized by using dynamical decoupling to allow for qudit high-bandwidth quantum communication and similar applications.
