“…Makino and Glinski have theoretically developed the normalized spontaneous emission power (per unit frequency bandwidth) for facet t(t = 1, 2). It can be expressed by the sum of the contributions from n sections as y; = IC; + (a, n where the transmission gain G of the whole structure can be written as (9) hf is the photon energy, nspm is the ratio of the spontaneous to stimulated emission for the mrh section and D = T22 + r l T 2 1 -r2T12 -r l r 2 T l l . (10) Here xh is the inverse differential quantum efficiency at the threshold [14].…”

Using a transfer matrix method, the results of analysis Of the spontaneous emission spectrum Of a three section phase controlled DFB laser are presented for implementing a continuously tunable optical filter. The influence of various parameters-net field gain, coupling coefficient, phase shift and reflection coefficients-on the spectrum behavior are studany mode jump. For this reason, a narrow spectrum selection (3.6 GHz) with a wide frequency tunability (33.3 GHz) was achieved while maintaining a constant gain and a 'Onstant gain bandwidth.A Phase controlled laser structure (one active section ied theoretically. The main-to subtransmission peak magnitude ratio can be chosen while varying the frequency, which demonstrates the tunability of the three-section phase controlled DFB laser filter. Analysis shows that a three section DFB laser (a passive phase shift control region between two DFB structures) presents a single-mode spontaneous emission spectrum operating over a wide continuous tuning range of less than 1 nm. The results of our work should aid in the design of multisection DFB laser filter.
