Antenna‐integrated quantum cascade lasers are extremely attractive as a compact method to couple the vibrational resonances in the mid‐infrared to nanometer‐sized biomolecules in an integrated form. The high sensitivity of such devices to extreme sub‐diffraction objects is demonstrated with a volume that is five orders of magnitude smaller than the cubic wavelength (λ 3 ). This suggests a new method to sense objects with extreme sub‐diffraction dimensions.
