Crystal growth and nonlinear optics

In those crystals, type-I and -II phase matching are usually the most suitable schemes. Types II and III are essentially equivalent, except that the names of signal and idler are swapped when the signal has a longer wavelength than the idler. One undesirable effect of angle tuning is that the optical frequencies involved do not propagate collinearly with each other. This is due to the fact that the extraordinary wave propagating through a birefringent crystal possesses a Poynting vector that is not parallel to the propagation vector.

Relevant Aspects for the Choice of Nonlinear Crystals

History[ edit ] The word 'photonics' is derived from the Greek word "phos" meaning light which has genitive case "photos" and in compound words the root "photo-" is used ; it appeared in the late s to describe a research field whose goal was to use light to perform functions that traditionally fell within the typical domain of electronics, such as telecommunications, information processing, etc.

These inventions formed the basis for the telecommunications revolution of the late 20th century and provided the infrastructure for the Internet. Though coined earlier, the term photonics came into common use in the s as fiber-optic data transmission was adopted by telecommunications network operators.

However, photonics covers a huge range of science and technology applications, including laser manufacturing, biological and chemical sensing, medical diagnostics and therapy, display technology, and optical computing. Further growth of photonics is likely if current silicon photonics developments are successful.

Relationship to other fields[ edit ] Classical optics[ edit ] Photonics is closely related to optics. Classical optics long preceded the discovery that light is quantized, when Albert Einstein famously explained the photoelectric effect in Optics tools include the refracting lensthe reflecting mirrorand various optical components and instruments developed throughout the 15th to 19th centuries.

Key tenets of classical optics, such as Huygens Principledeveloped in the 17th century, Maxwell's Equations and the wave equations, developed in the 19th, do not depend on quantum properties of light.

Modern optics[ edit ] Photonics is related to quantum opticsoptomechanicselectro-opticsoptoelectronics and quantum electronics. However, each area has slightly different connotations by scientific and government communities and in the marketplace. Quantum optics often connotes fundamental research, whereas photonics is used to connote applied research and development.

The term photonics more specifically connotes: The particle properties of light, The potential of creating signal processing device technologies using photons, The practical application of optics, and An analogy to electronics. The term optoelectronics connotes devices or circuits that comprise both electrical and optical functions, i.

The term electro-optics came into earlier use and specifically encompasses nonlinear electrical-optical interactions applied, e. Emerging fields[ edit ] Photonics also relates to the emerging science of quantum information and quantum optics.

Other emerging fields include: Optoacoustics or photoacoustic imaging where laser energy delivered into biological tissues will be absorbed and converted into heat, leading to ultrasonic emission.

Optomechanicswhich involves the study of the interaction between light and mechanical vibrations of mesoscopic or macroscopic objects; Opto-atomicsin which devices integrate both photonic and atomic devices for applications such as precision timekeeping, navigation, and metrology; Polaritonicswhich differs from photonics in that the fundamental information carrier is a polariton.

Polaritons are a mixture of photons and phononsand operate in the range of frequencies from gigahertz to approximately 10 terahertz.

A beryllium-free nonlinear optical (NLO) crystal K 3 Ba 3 Li 2 Al 4 B 6 O 20 F (KBLABF) with sizes up to 18 × 13 × 8 mm 3 was successfully grown by the top-seeded solution growth method using LiOH-H 3 BO 3 –BaF 2 flux.

The key limiting factors on the crystal morphologies and sizes were carefully analyzed.
