Materials scientists can learn a lot about a sample material by shooting lasers at it. With nonlinear optical microscopy — a specialized imaging technique that looks for a change in the color of ...

The invention is a method and process to create integrated nonlinear photonics, using the material tantalum pentoxide (Ta2O5, also known as tantala). CU researchers deposit tantala material on ...

Strike a bell, and the bell rings at its resonance modes. Strike it harder and the bell rings at the same tone, only louder. Now imagine a small crack in the bell, perhaps invisible to the eye. We ...

As mainstream materials for integrated optoelectronics, Silicon (Si), Silica (〖SiO〗_2), and Silicon Nitride (〖Si〗_3 N_4) are limited by their centrosymmetric crystal structures. Consequently, their ...
