“…Attention has been paid recently on the effects of optical injection on a special type of semiconductor laser: the vertical-cavity surface-emitting laser (VCSEL) [2][3][4][5][6][7][8][9][10]. VCSELs have demonstrated many impressive characteristics, including low threshold current, single-longitudinal mode operation, circular beam profile and easy fabrication in large two-dimensional arrays [2].…”

“…Emission in multiple transverse modes is usually found in solitary VCSELs [11] as a result of spatial-hole burning effect [12]. The effect of single-frequency optical injection on multi-transverse mode VCSELs has been also recently studied, showing that transverse mode selection or polarization switching can appear in these systems [7][8][9][10].…”

In this paper we report a new method of photonic generation of microwave signals using a multi-transverse mode VCSEL subject to two-frequency optical injection. Numerical simulations show that double injection locking involving two transverse modes can be obtained in these systems. We show that the higher-order transverse mode is excited with a much larger amplitude than that of the fundamental transverse mode. The comparison with the case of a single-transverse mode VCSEL subject to similar two-frequency optical injection shows that multi-transverse mode operation of the VCSEL enhances the performance of the photonic microwave generation system. Broad tuning ranges, beyond the THz region, and narrow linewidths are demonstrated in our system. The maximum frequency of the generated microwave signals can be substantially increased if multimode VCSELs are used instead of single-mode VCSELs.

“…Transmission distance as high as 90 km was achieved at 10 Gb/s by frequency chirp inversion and higher order transverse mode suppression [19]. Suppression of higher-order transverse modes in VCSELs induced by optical injection has been studied from experimental [19][20][21][22][23][24][25] and theoretical [24][25][26][27][28][29][30] points of view. Optical injection experiments in VCSELs have been usually performed using two different configurations.…”

“…In a different configuration, known as "parallel optical injection", linearly polarized light from an external laser source is injected parallel to the linear polarization of the solitary VCSEL [32]. Both, parallel [20][21][22] and orthogonal [23][24][25] optical injection have been used in experiments to suppress higher order transverse modes. Corresponding theoretical studies have been made for orthogonal [24][25] and parallel [26][27][28][29][30] optical injection configurations.…”

An experimental investigation of the modal selection induced by optical injection in 1550 nm multitransverse-mode VCSELs is performed. The free-running VCSEL emits in two transverse modes that are linearly polarized in a direction referred as parallel. We consider the situation in which parallel polarized laser light is injected in the VCSEL in order to select its fundamental transverse mode. We analyze the dependence of the modal selection process on the wavelength detuning between the externally injected signal and the fundamental mode. The injected power needed to select the fundamental mode as a function of the wavelength detuning is measured for several values of the bias current. This injected power exhibits a minimum at a positive wavelength detuning. The curves obtained for different bias currents are very close for positive and large wavelength detuning, while they are very separated for smaller detuning. The selection of the fundamental mode can be obtained with a value of the injected power that changes only slightly with the bias current when the wavelength detuning is large and positive. These results indicate that operation at large and positive wavelength detuning is of interest in the long-distance single-mode fiber transmission of multimode injection-locked VCSELs because the selection of the fundamental mode is obtained with an injected power that is almost independent on the VCSEL bias current. Both, the minimum injected power and the wavelength detuning at which it appears increase with the VCSEL bias current. We describe the relation between transverse mode selection and injection locking by comparing the dependence of both phenomena on the wavelength detuning. Modal selection is accompanied by injection locking only for large and positive values of the wavelength detuning. For small detuning values, with the VCSEL biased with a low (high) current, the injected power required for modal selection is lower (higher) than that needed for injection locking.
