Building Element and Method for Its Manufacture

Simple SummaryContent extracted from patent full text and abstract with AI.

This patent describes an optical component equipped with one or more specialized mirrors that have a sawtooth-shaped transition region. In these mirrors, the teeth become narrower and the connecting bridges between them become wider in a specific direction, eventually balancing each other out. This geometric arrangement enables both a reflective (mirror) function and a gradual, low-loss optical transition—crucial for efficiently connecting with waveguides or optical fibers. The design can be used in photon emitters, reflectors (including spin-state-dependent reflectors), and band filters.

Use CasesContent extracted from patent full text and abstract with AI.

• Efficient coupling of integrated photonic devices, such as lasers or photon emitters, to optical waveguides or fibers
• Quantum information or communication systems requiring precise single-photon sources with low coupling losses
• Photonic circuits where lossless transmission and precise reflection are required, such as in band filters or optical resonators
• Optical sensing or metrology systems integrating micro-optical components with external fiber networks
• Enhancing optical connectivity in chips for telecommunications or data centers

BenefitsContent extracted from patent full text and abstract with AI.

• Significantly reduces coupling losses between optical components, improving overall efficiency
• Supports adiabatic (gradual and low-loss) transitions between Bloch modes and waveguide modes, resulting in purer signal transmission and reception
• Enables dual-function mirrors that both reflect light and facilitate seamless connections to other components
• Mathematically optimized tooth geometry allows for tuning of optical properties according to application needs
• Adaptable for a variety of optical devices, including photon emitters, reflectors, and optical filters, enhancing design flexibility
• Potentially improves the performance of quantum devices by optimizing photon extraction and minimizing losses

Patent Abstract

The invention relates, inter alia, to a component (1) having at least one mirror (12). According to the invention, the mirror (12) has a sawtooth-shaped transition portion (122) comprising teeth (ZZ) which are interconnected via connecting portions (V) and are radially expanded in relation to the connecting portions (V); the radial width (ZW) of the teeth (ZZ) decreases in a specified direction, the radial width (SW) of the connecting portions (V) increases in the specified direction, and the tooth width (ZW) and the width (SW) of the connecting portion gradually become equal in the specified direction.
