Abstract

In fiber-optical telecommunications, wavelength division multiplexing (WDM) is a multiplexing and transmission scheme in which distinct wavelengths, each emitted by multiple lasers, carry specific information. WDM filters are used to multiplex these wavelengths. Similarly, at the receiving end, they are demultiplexed or separated using coherent detection with tunable local oscillators or similar filters. This paper explains the most recent applications of the WDM System in US patents. A succinct explanation of the WDM System is also given.

Abstract

Adaptive optics (AO) is defined as a technology developed to compensate for wavefront distortions caused by atmospheric turbulence or microscopic heterogeneities, thereby enhancing image quality in observational astronomy and biological microscopy. It utilizes devices such as deformable mirrors or spatial light modulators to detect and correct these distortions for improved imaging. In adaptive optics, a deformable mirror is incorporated into the optical system. This mirror measures wave aberration in real time to correct distortions, reducing environmental impacts and improving imaging quality. Essentially, adaptive optics actively corrects errors in optical systems, combining scientific principles with engineering applications to play a crucial role in modern optics. This paper serves as a review on adaptive optics.
