Ever since optical transport in the direct service of Internet Protocol (IP) became a preferred architecture in the mid-1990s, the holy grail of optical data researchers has been the fully connected ...

During the past few years, spectrally tunable lasers have been developed actively to address a number of applications. Several technologies are used for tunable laser such as external cavity laser, ...

Full-band tunable lasers are not a new topic in the communication sector. In fact, these lasers have been around for some time. But, while available, they have been only used in limited deployments in ...

Researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) and Technical University of Vienna (TU Wien) have invented a new type of tunable semiconductor laser that ...

At last month’s Lux-Enterprise Singapore Co-packaged Photonics/ASICS & Heterogeneous Integration Workshop, CompoundTek, a global foundry services provider in emerging silicon photonics (SiPh) ...

A new ring-based tunable laser on a chip emits multiple wavelengths smoothly, offering a compact, cost-effective alternative for sensing, diagnostics, and more. (Nanowerk News) Researchers in the ...

Figure 1. Schematic of a tunable microlaser based on phase-change perovskite gain medium, sandwiched between Au mirror and DBR reflector sitting on a quartz glass substrate, pumped by blue-violet ...

Lasers have widespread applications as a light source in a variety of fields, including manufacturing, medicine, high-speed communications, electronics, and scientific research. In recent years, the ...

DBR (Distributed Bragg Reflector) lasers are increasingly recognized for their versatility and effectiveness in tunable systems. These lasers enable precise wavelength adjustments, making them highly ...

A team at Harvard and Technical University of Vienna have invented a new tunable laser that uses a series of rings to smoothly emit many light wavelengths from a single chip. The laser could replace ...
