“…Acoustic waves are generated due to the process of electrostriction where high-intensity light wave traveling through a medium produces mechanical vibrations resulting in the scattered light and phonons [1]. The SBS has attracted considerable attention due to its adverse power limiting effect on the performance of optical networks [2]. Similarly, for high power fiber lasers, which have excellent properties, such as high beam quality, high efficiency, very high output power capability and ease of thermal management, however, the SBS is often considered as one of the main limitations [3].…”

However, the existence of the spurious solutions in full-vectorial finite element method has been a major problem for both acoustic and optic modal analyses. For emerging photonic devices exploiting light-sound interactions in high index contrast waveguides, this problem is a major limitation. A penalty function is introduced to remove these unwanted spurious modes in acoustic waveguides, which also identifies the acoustic modes more easily. Numerically simulated results also show considerably improved vector mode profiles. The proposed penalty method has been applied for the characterization of low index contrast single mode fiber and also for high index contrast silicon nanowire to demonstrate its effectiveness.

The generation of high‐order Brillouin Stokes is experimentally demonstrated in 300 km all‐Raman transmission with normal Raman pumps and without mirror reflection, and a longest ever fiber laser is implemented at the same time. The OSNRs of the two Brillouin Stokes after 300 km are both higher than 29 dB. © 2007 Wiley Periodicals, Inc.

The fibre-optic microwave photonic link has become one of the basic building blocks for microwave photonics. Increasing the optical power at the receiver is the best way to improve all link performance metrics including gain, noise figure and dynamic range. Even though lasers can produce and photodetectors can receive optical powers on the order of a Watt or more, the power-handling capability of optical fibres is orders-of-magnitude lower. In this paper, we propose and demonstrate the use of few-mode fibres to bridge this power-handling gap, exploiting their unique features of small acousto-optic effective area, large effective areas of optical modes, as well as orthogonality and walk-off among spatial modes. Using specially designed few-mode fibres, we demonstrate order-of-magnitude improvements in link performances for single-channel and multiplexed transmission. This work represents the first step in few-mode microwave photonics. The spatial degrees of freedom can also offer other functionalities such as large, tunable delays based on modal dispersion and wavelength-independent lossless signal combining, which are indispensable in microwave photonics.
