“…Finally, the proposed application of acoustic nonlinearities in photonics further contributes to the ongoing effort to complement and strengthen optical nonlinearities with nonlinear effects of other nature such as, for example, nonlinearities of spin waves [180]. These developments may lead to interesting fundamental physics because both sound and spin wave excitations can simultaneously interact with light [123].…”

Nonlinear optical processes are vital for fields including telecommunications, signal processing, data storage, spectroscopy, sensing, and imaging. As an independent research area, nonlinear optics began with the invention of the laser, because practical sources of intense light needed to generate optical nonlinearities were not previously available. However the high power requirements of many nonlinear optical systems limit their use, especially in portable or medical applications, and so there is a push to develop new materials and resonant structures capable of producing nonlinear optical phenomena with low-power light emitted by inexpensive and compact sources. Acoustic nonlinearities, especially giant acoustic nonlinear phenomena in gas bubbles and liquid droplets, are much stronger than their optical counterparts. Here, we suggest employing acoustic nonlinearities to generate new optical frequencies, thereby effectively reproducing nonlinear optical processes without the need for laser light. We critically survey the current literature dedicated to the interaction of light with nonlinear acoustic waves and highly-nonlinear oscillations of gas bubbles and liquid droplets. We show that the conversion of acoustic nonlinearities into optical signals is possible with low-cost incoherent light sources such as lightemitting diodes, which would usher new classes of low-power photonic devices that are more affordable for remote communities and developing nations, or where there are demanding requirements on size, weight and power. . 1: (a) Generation of new optical frequencies via a nonlinear optical interaction. High-power monochromatic laser light interacts with the nonlinear optical medium, e.g. a dielectric microresonator, to generate new optical frequencies [9]. (b, c) The nonlinear properties of sound can be used to generate optical nonlinearities without the need for high-power laser light. Low-power light couples to a sound wave via a deformable fluid, e.g. gas bubble or liquidmetal nanoparticle, exploiting strong nonlinear acoustic effects. This converts acoustic frequencies to the optical domain, effectively reproducing the result of the nonlinear optical interaction in (a). Images from www.freeimages.com and www.dreamstime.com. FIG

“…Finally, magnons offer a great advantage since spin wave wavelengths are orders of magnitude smaller than the wavelengths of electro-magnetic waves in the same GHz range, which allows for miniaturization of future oscillator devices. Earlier theoretical developments and pioneering proofof-concept reports, especially from Kalinikos and colleagues [40][41][42][43][44] , have shown the feasibility of such "magnetically tunable" microwave optoelectronic oscillators. However, a comprehensive tehnical examination of such a hybrid system is lacking.…”

“…Here, it is continuously tuned by the attenuation level, A, of the loop via a variable microwave attenuator. Earlier works using a YIG feedback loop were conducted under either a fixed V [42][43][44] or H 48 , thus the G is a fixed number throughout the discussion. Here, due to the different auto-oscillation thresholds of the feedback loop with respect to changing V,H, the gain will have to be defined differently for each scenario.…”

We report the construction and characterization of a comprehensive magnonic-opto-electronic oscillator (MOEO) system based on 1550-nm photonics and yttirum iron garnet (YIG) magnonics. The system exhibits a rich and synergistic parameter space because of the ability to control individual photonic, electronic, and magnonic components. Taking advantage of the spin wave dispersion of YIG, the frequency self-generation as well as the related nonlinear processes become sensitive to the external magnetic field. Besides being known as a narrowband filter and a delay element, the YIG delayline possesses spin wave modes that can be controlled to mix with the optoelectronic modes to generate higher-order harmonic beating modes. With the high sensitivity and external tunability, the MOEO system may find usefulness in sensing applications in magnetism and spintronics beyond optoelectronics and photonics.
