Perovskite has attracted considerable attention in the electronic and optical fields in recent years, fulfilling the requirements of the ever‐growing demand in energy, environment, security, and big data storage. Laser direct writing technology is a flexible and mask‐free approach for fabricating, structuring, modifying, and patterning perovskites. Laser irradiation can directly induce perovskites from precursors due to the photothermal and photochemical effects of laser. Therefore, various laser‐induced perovskites, such as perovskite quantum dots, nanowires, nanocrystals, and films, are summarized. In particular, the laser‐induced perovskites in glass are intensively investigated for their high stability and flexibility in 3D printing. The second part of this review examines various applications of perovskites based on laser technology, such as solar cells, flat lenses, microlasers, photoluminescence, lithography, sensors, optical encryption, and data storage. Diverse laser treatments employed for modulating and patterning perovskite devices, such as laser annealing, laser ablation, and laser‐induced defects, are discussed. Prospective challenges and future trends in this research field are also concluded.

“…El líquido se comporta como una red de fase, dando lugar a un patrón de difracción (efecto acusto-óptico) [16]. El efecto acustoóptico es utilizado para diversas aplicaciones, como microscopía e imágenes biomédicas [17] [18], fotónica integrada en niobato de litio [19], o giróscopos de onda progresiva [20].…”

En trabajos anteriores presentamos un novedoso sensor multiparamétrico que mide simultáneamente el índice de refracción y la velocidad del sonido en un líquido aprovechando el efecto acusto-óptico. El sensor requiere un sistema de iluminación que expanda el haz láser de manera tal que interactúe eficazmente con el líquido bajo estudio. Por otra parte, también es necesario un sistema de proyección a fin de capturar adecuadamente el patrón de difracción a la salida de la celda. En este sentido, en este artículo, presentamos la optimización del sistema de iluminación y proyección del sensor utilizando la herramienta computacional de diseño óptico Zemax OpticStudio. El rango considerado de índices de refracción de las muestras líquidas está comprendido entre 1,33 y 1,51. Como resultado se obtuvo una correcta expansión del haz incidente sobre la celda, y el sistema de proyección logra una imagen con muy pocas aberraciones y una separación angular adecuada entre los máximos del patrón de difracción. A su vez, las dimensiones resultantes del sensor luego de la optimización del sistema de iluminación y proyección permiten afirmar que es compacto y portable.

“…While LN devices have been widely adopted for telecommunication and RF signal processing in the past decades, the large optical mode size and weak optical confinement in LN waveguides prevent its further development in integrated nanophononics. Recently, thin-film LN (TFLN) has emerged as a promising platform for high-performance photonic devices. – The TFLN devices have submicron waveguide with high refractive index contrast and small mode size, which largely decrease the electrode length and microwave losses, thereby breaking the fundamental bandwidth limit in bulk LN devices. – High-performance TFLN modulators with low operating voltages, ultrahigh working bandwidths, and compact footprints have been widely reported. – Moreover, a ring-loaded MZI modulator in TFLN has presented the breakthrough of the bandwidth limit in a high quality factor ( Q ) ring with coupling modulation, , which is a significant improvement for future high-density integration in a TFLN platform. However, simultaneous and independent control of the extinction ratio and wavelength in TFLN is yet to be demonstrated.…”

On-chip optical filters are of key importance to many modern applications such as optical interconnections and wavelength division multiplexing systems. In all these scenarios, simultaneous tunability of the extinction ratio and working wavelength is particularly essential for the optical filters to construct the optical networks but remains a scientific challenge. Here, we demonstrate a novel optical filter on the thin-film lithium niobate platform, where both the extinction ratio and working wavelength can be simultaneously and independently tuned by adjusting two loaded electro-optic modulators. The device demonstrates the tunability of the extinction ratio from 0 to over 25 dB at a fixed working wavelength. On the other hand, the filter, with a footprint of 1.2 mm × 0.65 mm, also shows over 100 pm linewidth with a resonant wavelength tunability of 12.5 pm/V at the critical coupling condition.
