← ScienceWhich consequence results when laser coherence degrades within integrated photonics?
A)Increased crosstalk between waveguides✓
B)Improved thermal stability overall
C)Enhanced signal propagation distance
D)Reduced backscattering interference noticeably
💡 Explanation
Increased crosstalk emerges because loss of coherence diminishes the precise phase relationship between optical signals in adjacent waveguides; this causes unintentional signal coupling via mode overlap, resulting in crosstalk, therefore increased crosstalk rather than improved stability because coherence impacts phase consistency.
