Breakthrough: Engineers Create Revolutionary Integrated Optical Isolator

Engineers at the Harvard John A. Paulson School of Engineering and Applied Sciences have developed an integrated optical isolator that can improve the performance of optical systems used in telecommunications, microscopy, imaging, and quantum photonics. The isolator, made of lithium niobate, allows light emitted by a laser to propagate unaltered while redirecting reflected light away from the laser. The device offers the best optical isolation performance and competitive metrics in terms of loss, power efficiency, and tunability. The breakthrough could lead to smaller, more efficient optical chips and revolutionize various fields of work.

Analyzing the Economic Impact of Removing Space Debris.

A NASA study has found that some methods of removing orbital debris could pay for themselves within a decade by reducing the costs and risks borne by satellite operators. The most effective approaches involved ground- and space-based lasers to remove large amounts of small debris between 1 and 10 centimeters across. The study also found that the relatively small costs that debris imposes on satellite operators today, estimated at $58 million a year, mean that the risk to satellite operators need not increase at the same rate as orbital debris increases.
