High-sensitivity optical fiber magnetic field and current sensor based upon two cascaded Mach-Zehnder interferometers

In this article, we have designed a highly sensitive S1 that can measure magnetic field (MF) and current. S1 consists of two Mach-Zehnder interferometers (MZIs) cascaded together, namely, MZI1 and MZI2. MZI1 and MZI2 have simple structures and are fabricated by directly tapering...
