Abstract

See full text

A device includes a first resonating cavity and a second resonating cavity. The first resonating cavity includes a first end surface and a second end surface. The first resonating cavity has a first free spectral range. The first free spectral range is a first frequency of a wavelength dependent ripple in a gain of the device that is a function of a first distance between the first end surface and the second end surface. The second resonating cavity includes a third end surface and a fourth end surface. A second distance between the third end surface and the fourth end surface is set such that an amplitude of the wavelength dependent ripple is reduced.
