Harvard researchers have demonstrated a special type of optical frequency comb, called a normal-dispersion Kerr microcomb, on a thin-film lithium niobate chip, allowing for frequency comb generation and electro‑optic modulation to be combined on a single, compact platform.
Harvard researchers have developed OpenMetabolics, an open-source, smartphone-based activity monitor that uses machine learning and leg motion to estimate calories burned.
Harvard researchers report a new way to make ultra-smooth, microscopic mirrors that form high-performance optical resonators, or cavities.
