A noble idea is used to propose a wavelength tunable tilted Fiber Bragg Gratings based microwave sensor using surface plasmon resonance. The Bragg wavelength shifts linearly about 6 pm/°C, due to the temperature change. This temperature variation occurs because of the microwave–metal interaction at cladding layer of the optical fiber based proposed sensor. The wavelength tuning can be achieved by using tilted Fiber Bragg Gratings. To use the wavelength sources of 850 nm, 1310 nm and 1550 nm, tiled Fiber Bragg Gratings with grating periods of 293.65 nm, 452.56 nm and 535.47 nm respectively are required in the same fiber with certain distances among them
